Bernie Sanders beats Hillary Clinton in Wisconsin: It's about authenticity, stupid

It was never supposed to be this close.
Bernie Sanders’ win Tuesday in Wisconsin adds another victory to his impressive total and raises the question of whether or not this process is making Hillary Clinton stronger or is exposing her very real vulnerabilities.
There’s one metric that has consistently worked in Sanders’s favor and has decided many primaries: authenticity. In Tuesday’s exit polls, Wisconsin Democrats said by a margin of 82 percent to 16 percent that Sanders was more honest and trustworthy than Clinton. And while she beat Sanders 85 percent to 14 percent in terms of which candidate had the right experience for the job, voters ranked honesty and trustworthiness as their number one issue. The second most important issue? It was “cares about people like me” – another winning category for Sanders.
This will continue to plague Clinton throughout the primaries and, indeed, the general election. It’s not just the email scandal or her speeches at Goldman Sachs or flip flopping on key issues to Democrats like trade agreements. It’s an overwhelming feeling that Clinton operates in her own self interest as opposed to the good of the many and that she is, fundamentally, inauthentic.
That feeling appears to be overwhelming the electorate in many states.
To be sure, the states that Bernie Sanders is winning are largely white and tend to be more liberal. Clinton continues to consistently win African-American and Latino voters, two key voting blocs that will help her as the race moves to more diverse states again.

But in a campaign that has been so driven by momentum, Wisconsin certainly helps Sanders as he heads to New York. He already raised an astounding $44 million in March and will no doubt do the same in April. And though New York is Clinton’s adopted home-state after serving as senator there, Sanders is making inroads. He’s now only 12 points behind Clinton when he was upwards of 40 points behind her just a few months ago.
Momentum is the reason that the Sanders campaign is now talking about Clinton not getting the delegates she needs to win the nomination before the convention, and making the case to super-delegates that they should support him over her.
His team has been invoking 2008 when super-delegates left Clinton for Obama. That scenario was decidedly different in that Obama was the frontrunner for much of the race and Sanders will not be the frontrunner as we head into Philadelphia.
But Sanders will have a case if he manages to keep up this pace and pull off some bigger wins – he needs larger margins to make a dent in her delegate count – and therefore argue that the electorate is behind him; or at least behind him enough that they should think twice.
The odds of this scenario playing out are still quite unlikely. Tuesday’s win won’t seriously hurt Clinton as Wisconsin splits delegate proportionally. That said, an increasingly close race in New York, where a Sanders’s rally at Washington Square Park is scheduled just five days before the primary, is certainly unsettling for the Clinton camp.
We’ll say it again. It was never supposed to be this close.

Why Trump and Clinton are suddenly stumbling despite their huge leads

It’s a rather remarkable phenomenon: The two front-runners are having trouble closing the deal.
By this point in the campaign, Donald Trump and Hillary Clinton should be thinking about running mates and planning for the fall. Instead, they both had their hands full trying to stave off defeat in Wisconsin.
And both campaigns, in an apparent sign of frustration, put out preemptive memos defending their positions against the press and the prognosticators.
Ted Cruz easily won Wisconsin yesterday, a symbolically important victory even though only 42 delegates were at stake. And Bernie Sanders romped in Wisconsin, with Fox calling the race as soon as the polls closed at 8 p.m. central.
Trump was on an incredible roll two weeks ago, having won 20 states and driven all but two rivals out of the race. Instead, Wisconsin gave a big psychological boost to Cruz, who captured his first major primary outside his home state of Texas.
But it’s important that the pundits not go overboard here. Trump is still going to the convention with a big lead, even if yesterday’s contest made it slightly harder for him to get to 1,237.  Cruz has almost no hope of reaching the magic number and would have to win the nomination after the first ballot.

Many forces combined to deny Trump the win. The GOP establishment, in this case led by Scott Walker, did everything it could to derail him. He made a series of missteps, from abortion comments that ticked off the pro-life and pro-choice sides to retweeting an unflattering photo of Cruz’s wife. The press smelled blood in the water.
And maybe Wisconsin was never a great state for Trump. Although some areas have plenty of blue-collar workers, its voters are, on average, better educated and more religious than in most other states, and that isn’t The Donald’s base.
Little wonder, then, that Trump senior adviser Barry Bennett complained in a leaked memo that the “pathetic” and “idiotic” media were exaggerating the candidate’s problems.
Cruz also deserves credit for staying on message, garnering support from politicians who don’t much like him, and counterpunching without getting too personal (except for the “sniveling coward” moment).
Clinton’s loss is even more inexplicable. She has now been beaten in six out of seven contests by a 74-year-old self-proclaimed socialist who never should have been much of a rival.
The media have focused far less on the Democratic race because of a nearly universal conviction that Clinton, regardless of her stumbles, is a lock to win the nomination.
But strange things are happening. Bernie raised $15 million more than Hillary last month, and he hasn’t held a single fundraiser. Grass-roots liberals are filling his coffers, despite the widespread chatter that he will lose, while Hillary holds big-money events that further brand her as the candidate of the monied establishment.
Clinton campaign manager Robby Mook felt compelled to issue a pre-Wisconsin memo insisting that “Hillary Clinton has built a nearly insurmountable lead among both delegates and actual voters. Contrary to the claims of the Sanders campaign, in measure after measure, Clinton has shown the broadest support of any candidate currently running for president.”
And yesterday, when Sanders’ top aide told CNN his campaign would work on flipping superdelegates at the Philadelphia convention, Hillaryland sent out a blast saying he wants to overturn the will of the voters.
Wisconsin fit the Sanders formula, a predominantly white state with a strong progressive tradition. But he is the one generating the big crowds and excitement, while she increasingly sounds like the Hillary of 2008, promising sensible change and scoffing at the inspirational rhetoric of her opponent.
Oddly enough, the Sanders team conceded in a lengthy New York Times piece that had the senator been more aggressive against Clinton in 2015 and spent more time on the trail, he might be well positioned now to win. Although Hillary might have responded in kind if Sanders had whacked her over the email scandal and other matters, the story read like a post-mortem reflection on defeat.
So how is it that Trump and Clinton have hit this rough patch?
They could not be more different. Trump is the bombastic outsider with no political experience, Clinton the consummate insider since her days as first lady.
Trump mostly wings it; Clinton speaks in position-paper paragraphs. Trump is entertaining; Clinton, who says she’s not a natural politician, can be dull. He speaks the language of a native New Yorker; she sounds like a former New York senator.
Clinton met with world leaders as a globe-trotting diplomat; Trump has built hotels and golf courses around the world.
But they share one thing in common: high negatives. They would, according to current polls, be the most unpopular major-party nominees in memory. Trump has high unfavorable ratings from women; Clinton, despite her gender advantage, has had trouble winning over younger women.
And that, in a nutshell, is why neither one has been able to wrap things up.

Cruz, Sanders pick up convincing wins over Trump, Clinton in Wisconsin

 Republican Sen. Ted Cruz and Democratic Sen. Bernie Sanders scored big victories in Wisconsin's presidential primaries Tuesday, dampening Donald Trump and Hillary Clinton's hopes of wrapping up the race any time soon -- and putting heavy pressure on the front-runners to recapture the momentum in contests later this month. 
Both Cruz and Sanders charged out of Wisconsin claiming momentum was turning in their favor. Sanders, who notched his sixth victory in the last seven state contests, won all but three of the Badger State's 72 counties.
“And we have won almost all of them with overwhelming, landslide numbers,” Sanders told an ebullient crowd of supporters Tuesday night.
Sanders was speaking in Wyoming, which holds a caucus contest this weekend. But the next big primary will be in New York on April 19, and Sanders has vowed to take on Clinton in her adopted home state.
Cruz also pointed to his win Tuesday as a sign the tides are turning against Republican front-runner Trump, who faced one of the roughest weeks of his campaign going into the primary.
"Tonight is a turning point," Cruz declared at a rally in Milwaukee. "It is a rallying cry. It is a call from the hard-working men and women of Wisconsin to the people of America: we have a choice. A real choice."

Yet Cruz, despite winning in Wisconsin and outmaneuvering Trump lately in the grueling battle for delegates, still faces challenging terrain in the weeks ahead. Trump has a clear lead in New York polls, and his campaign claimed "total confidence" they would win that race.
Trump's campaign also put out a biting statement Tuesday night that said Cruz was "worse than a puppet--- he is a Trojan horse, being used by the party bosses attempting to steal the nomination from Mr. Trump."
Even if Trump holds his ground in New York, however, Cruz's Wisconsin win only increases the odds that the Republican Party will hold its first open convention in four decades this July, a scenario Trump seemed to be referring to.
Any candidate would need 1,237 delegates to clinch the nomination before then, and Cruz's Wisconsin victory makes that number very difficult for Trump to obtain.
With 99 percent of precincts reporting, Cruz led with 48 percent of the vote to Trump's 35 percent. Ohio Gov. John Kasich was trailing far behind on 14 percent of the vote.
Exit polls showed disquiet about Trump among Wisconsin Republicans. In the Fox News survey of 1,532 primary voters, 58 percent of respondents said they were either concerned or scared about the prospect of Trump being elected president. More worryingly for the Trump campaign, 37 percent said they would not vote for him if he faced Clinton in November's general election.
On the Democratic side, returns showed Sanders with 56 percent of the vote to Clinton's 43 percent with 99 percent of precincts reporting.
The victory helps fuel Sanders' argument that the Democratic primary is far from over, even as front-runner Clinton tries to turn her attention to the general election.
Exit polls in the Democratic race show Sanders won in part with the help of independent voters, 72 percent of whom broke for the Vermont senator.
While the Cruz and Sanders wins in Wisconsin won't necessarily shorten the odds on either winning their party’s nomination, the losses by the front-runners keep an aura of uncertainty hanging over both races.
Cruz, enjoying the support of Wisconsin Gov. Scott Walker, campaigned harder than anybody in the Midwestern state. Buoyed by conservative talk show hosts and others opposed to a Trump bid, the Texas senator led in most GOP polls leading up to Tuesday’s primary.
For Trump, the long lead-up to Wisconsin's contest has included one of the worst stretches of his candidacy. He was embroiled in a spat involving Cruz's wife, which he now says he regrets, was sidetracked by his campaign manager's legal problems after an altercation with a female reporter, and stumbled awkwardly in comments about abortion.
Still, Trump made a spirited final push in the state. His campaign said Tuesday night he withstood an "onslaught of the establishment" in Wisconsin.
Complicating the primary landscape for both Cruz and Trump is the continuing candidacy of Kasich. The Ohio governor's only victory has come in his home state, but he's still picking up delegates that would otherwise help Trump inch closer to the nomination or help Cruz catch up.

Trump has joined Cruz in calling for Kasich to end his campaign. But Kasich cast Trump's focus on him as a sign that he's best positioned to win over the businessman's supporters.
For Republicans, 42 delegates were at stake Tuesday. According to an Associated Press count late Tuesday, Cruz won 33 of 36 allocated Wisconsin delegates, with Trump winning the other three and six delegates still outstanding. With the latest results factored in, Trump has 740 delegates to Cruz's 514. Kasich is a distant third with 143 delegates.
For Democrats, 86 delegates were on the line Tuesday in Wisconsin. With his victory, Sanders won 45 delegates to Clinton's 31, with 10 delegates outstanding, according to an Associated Press count. When including superdelegates, the party officials who can back any candidate, Clinton holds 1,743 delegates to Sanders' 1,056. It takes 2,383 delegates to win the Democratic nomination.
On the eve of voting in Wisconsin, Clinton's campaign manager argued that Sanders' only path to victory "relies on overturning the will of the voters." In a memo to supporters, Robby Mook wrote that Sanders' strategy now is "a combination of trying to flip pledged delegates at state and county conventions, while also convincing superdelegates that he deserves their support."

Clinton, Sanders agree to Democratic debate in Brooklyn before New York primary

NEW YORK –  Hillary Clinton and Bernie Sanders have agreed to a Democratic presidential debate next week in New York, ensuring a high-stakes televised showdown ahead of the state's influential primary.
The two campaigns confirmed Monday the candidates would appear at the debate April 14 in Brooklyn, New York, putting the Democratic rivals onstage together before New York's April 19 primary.
Clinton, a former New York senator, holds a significant lead over Sanders among delegates, but the Vermont senator is hoping a win in Tuesday's primary in Wisconsin will build more momentum againstClinton in her adopted home state. Sanders has won five of the past six states to hold contests.
The announcement by CNN that it would host the debate ended days of acrimonious negotiations, with both sides accusing each other of playing games with the proposed forum. Sanders' campaign said it agreed to move a major New York City rally scheduled for April 14 to the night before so Sanders could attend the debate.
CNN said it will partner with Time Warner Cable's NY1, a channel focused on New York news.
Both candidates have personal ties to the debate site. Sanders was born and raised in Brooklyn, whileClinton's campaign's headquarters is based in Brooklyn, about a mile from the debate site at the Brooklyn Navy Yard's Duggal Greenhouse.

Trump faces new headaches in behind-scenes battle for delegates

While North Dakota is a most unlikely place for the Republican presidential campaign to take a critical turn, it nonetheless delivered an apparent setback over the weekend to front-runner Donald Trump in the behind-the-scenes battle for delegates, as Ted Cruz declared victory at the northern border state's GOP convention.
Like most states where Cruz has claimed victory, North Dakota is relatively light on delegates. Trump’s wins in delegate-rich primary states have kept the billionaire businessman well ahead, and the events in Fargo won’t change that.
But the North Dakota showdown speaks to the organizational headwinds Trump is facing – something he’s also dealing with in Wisconsin, which holds its primary Tuesday and where Cruz is polling in front. And if nothing else, the North Dakota convention results could put Cruz in a better position at the party’s July convention if the nomination is still open going into Cleveland.
"I'm thrilled to have the vote of confidence of Republican voters in North Dakota who delivered such a resounding victory today,” Cruz said in a statement. “Whether we defeat Donald Trump before the convention or at it, I'm energized to have the support of the vast majority of North Dakota delegates."
The vote in North Dakota was not a traditional primary or caucus, but a convention. Delegates chosen over the weekend through an internal party process will not be “bound” to any candidate. For that reason, there technically was no winner from the weekend’s gathering.
Yet the presidential candidates still scrambled to try and get their own supporters elected as delegates, banking on their loyalty at the July convention.

In the end, the Cruz campaign claimed that 18 of the 25 delegates selected Sunday are supporters of the Texas senator.
The Trump campaign, though, disputed this, claiming some of those listed as Cruz supporters were actually undecided. One Trump source went so far as to call Cruz’s claims “bull,” saying the senator only has four dedicated supporters of the 18.
The campaign further claimed Sunday that they came into Fargo with “zero expectations” but were “encouraged by the results” in the end.
“Nearly one-third of Sen. Cruz's ‘list’ was not elected, and many of those elected from his ‘list’ are firmly undecided or support other candidates,” the Trump campaign said in a statement, while also touting an endorsement from Rep. Kevin Cramer, R-N.D.
The campaign said supporter and former GOP primary candidate Ben Carson “privately met with many of the undecided delegates, and we're confident that we will receive strong support from the delegation in Cleveland.”

And John Weaver, strategist for Ohio Gov. John Kasich, took to Twitter to claim Cruz’s “strong-arm tactics” failed in North Dakota, saying he “helped elect delegates who will vote” for Kasich in Cleveland.
For whom the 25 delegates in Cleveland will vote remains an open question, as they are not bound to anybody. Some listed as Cruz supporters were actually “leaning” toward him, and not necessarily committed.

But the anti-Trump organizing in Fargo was nevertheless robust.
One anti-Trump group, Our Principles PAC, was heavily involved on the ground in Fargo, deploying a field team to speak to convention attendees and distribute hundreds of voter guides to make the case against Trump.
"This campaign is coming down to a ground game battle for delegates,” PAC senior adviser Brian Baker said in a statement. “We will fight for every last delegate vote all the way to Cleveland.  We are committed to making sure Donald Trump is not the Republican nominee and that the GOP wins the White House this fall with a principled conservative. Republicans at the North Dakota Convention rejected Trump, just like the entire Republican base will do this summer in Cleveland."
It’s these forces that Trump also is facing down in Wisconsin, which holds its primary on Tuesday. Cruz has led in most recent Wisconsin polls.
Trump is fighting to clinch the nomination before July with the requisite 1,237 delegates, while his remaining rivals try to hold him under that threshold.
Yet the front-runner has faced other setbacks in the grueling battle for each and every delegate. Recently in Louisiana, Trump has vowed to both file a lawsuit and an internal challenge within the Republican National Committee over reports that Cruz, despite losing the Louisiana primary to Trump in early March, could draw the support of enough “unbound” delegates and from Rubio supporters to actually overtake Trump in the state by as many as 10 delegates.
And The Tennessean reports that the Trump campaign is now accusing the Tennessee GOP of trying to stop pro-Trump delegates from being part of the state’s convention delegation.
Trump won the state’s primary, but a state party arm is responsible for appointing 14 of the 58-person delegation. The Trump camp reportedly alleges “anti-Trump” people have made their way onto the delegate list.
"They're picking establishment picks who don't support Donald Trump, and it's just the same effort that they're conducting all over the country to steal a vote here, steal a delegate there, to affect the outcome of the convention in July and take the nomination away from Donald Trump,” Darren Morris, Trump’s Tennessee state director, told the newspaper.

Trump, Cruz pressure Kasich to exit GOP primary race

Donald Trump and Ted Cruz don’t agree on much, but they seem to have come together on one point: John Kasich should get out.
Both Republican presidential candidates have turned up the pressure on Kasich, casting the Ohio governor as a nuisance candidate whose presence in the race is only frustrating their efforts to snag the nomination.
"If I didn't have Kasich, I automatically win," Trump claimed Sunday evening in West Allis, Wis.
Even Texas Sen. Cruz, who is second to Trump in the delegate race and eager to whittle the contest down to a two-man battle in the final weeks before the convention, is losing patience with what he describes as Kasich’s “spoiler” bid.
On Monday, Cruz said talk of someone other than him or Trump winning the Republican nomination at a contested convention is "nothing less than a pipe dream."
The complaints are building ahead of Wisconsin’s primary on Tuesday.

It’s yet another contest that Kasich, who has won only his home state of Ohio, likely has no shot at winning. But Kasich’s out-in-the-open strategy is not to win in the traditional, state-by-state way -- but prevent his rivals from clinching the nomination with the requisite 1,237 delegates, in order to trigger a contested convention in Cleveland.
Monday night in an "On The Record" town hall hosted by Fox News' Greta Van Susteren, Kasich said, "Both of them say I ought to get out of the race because I'm winning their votes. I agree with them."
He said that nobody will reach the requisite delegates for the nomination going into the convention, and that an open convention will decide the nominee."There's gonna be an open convention and it's gonna be cool...and the delegates are going to decide who can win in the fall," he said.
The two candidates with a more plausible path to the nomination – particularly Trump – are signaling the time has come, though, for Kasich to get out.
Trump said Sunday it was unfair for Kasich to continue campaigning. He suggested Kasich follow the lead of former candidates Marco Rubio and Jeb Bush -- and quit. He said earlier Sunday he had shared his concerns with Republican National Committee officials at a meeting in Washington this past week.
The Kasich campaign, though, is wearing the complaints as a badge of honor.
Kasich chief strategist John Weaver sent a fundraising email highlighting Trump’s claim that he’d win if Kasich dropped out.
“Talk about a validator for what you and I know to be true - these guys are terrified to face Gov. John Kasich at a convention …” the email said.
As of Monday afternoon, Trump had 736 delegates, Cruz had 463 and Kasich had 143.
For Trump, Kasich’s presence in the race represents one of numerous challenges to his efforts to lock down the nomination before July. While Trump by far has won more states than anybody else, Kasich and Cruz both have helped slow his accumulation of delegates.
Further, Cruz has worked to solidify a backup plan in case the convention truly is contested.
The Washington Examiner reported Monday that the latest battleground is Arizona, a state Trump already won but where Cruz is actively recruiting candidates for delegate slots – who potentially could back Cruz in the event of a floor fight.
This, after Cruz claimed victory at North Dakota’s under-the-radar GOP convention over the weekend. While the 25 delegates selected at that convention are not bound to any candidate, Cruz claimed more of his supporters were elected than anybody else’s.
While Kasich defends his presence in the race, Cruz told Fox News that Kasich at this point is “mathematically eliminated” and right now is only playing the role of “spoiler.”
“A vote for Kasich is a vote for Donald Trump,” Cruz said. “You cannot be the nominee if you lose every state other than your home state.”
Meanwhile, the race in Wisconsin is turning out to be a tough haul for the two primary front-runners. Cruz is leading most GOP polls in the state, while Vermont Sen. Bernie Sanders is leading Hillary Clinton in some polls on the Democratic side.
An upset for the front-runners in Wisconsin could be problematic because the next big contest on the primary calendar is delegate-rich New York, which votes April 19. Trump still has a comfortable lead in the Empire State, but Sanders has threatened to close the gap against Clinton on the Democratic side.
In a sign of the tension in that race, Clinton and Sanders announced they'd agreed to debate in New York before the primary, though their campaigns continued debating over when to schedule the face-off.
On the Republican side, Trump's call for Kasich to bow out came as Republican concerns grew about the prospect of convention chaos if Trump fails to lock up his party's nomination -- or even if he does.
Behind Cruz in the polls in Wisconsin, Trump faces the prospect that a loss on Tuesday there will raise further doubts that he can net the needed delegates, making it far easier for his party to oust him in a floor fight at the convention in Cleveland in July.
Kasich acknowledges he cannot catch up in the delegate race, leaving a contested convention his only path to victory. Still, Kasich suggested that a contested convention would not involve the chaos that party leaders fear.
"Kids will spend less time focusing on Bieber and Kardashian and more time focusing on how we elect presidents," Kasich told ABC. "It will be so cool."

Cruz, Sanders look to keep pressure on front-runners with Wisconsin wins

Senators Ted Cruz and Bernie Sanders will hope that their underdog campaigns get a boost from Wisconsin voters in the state's primary Tuesday.
Most polls show Cruz leading Republican front-runner Donald Trump in the Badger State. The Democratic race appears to be much closer, but recent polls have shown Sanders, the self-described democratic socialist, holding a slight lead over Hillary Clinton.
While Sanders remains a force in the Democratic primary, a win in Wisconsin would do little to significantly cut into Clinton's lead in delegates that will decide the party's nomination. The stakes are higher for Cruz, who trails Donald Trump in the GOP delegate race and sees Wisconsin as a crucial state in his effort to push the party toward a convention fight.
"We are seeing victory after victory after victory in the grassroots," Cruz said during a campaign stop Monday. "What we are seeing in Wisconsin is the unity of the Republican Party manifesting."
Losses for Trump and Clinton in Wisconsin could be problematic with the next big contest on the primary calendar, in delegate-rich New York, not until April 19. Trump still has a comfortable lead in the Empire State, but Sanders has threatened to close the gap against Clinton on the Democratic side.
For Trump, the long lead-up to Wisconsin's contest has included one of the worst stretches of his candidacy. He was embroiled in a spat involving Cruz's wife, which he now says he regrets, was sidetracked by his campaign manager's legal problems after an altercation with a female reporter, and stumbled awkwardly in comments about abortion.

While Trump is the only Republican with a realistic path to clinching the nomination ahead of the Republican convention, a big loss in Wisconsin would greatly reduce his chances of reaching the 1,237 delegates needed to do so before the GOP gathers in Cleveland.

Cruz headed into Tuesday's contest with the backing of much of the state's Republican leaders, including Gov. Scott Walker, but Trump made a spirited final push in the state and predicted a "really, really big victory."

"If we do well here, it's over," he said. "If we don't win here, it's not over."

Complicating the primary landscape for both Cruz and Trump is the continuing candidacy of John Kasich. The Ohio governor's only victory has come in his home state, but he's still picking up delegates that would otherwise help Trump inch closer to the nomination or help Cruz catch up.

Trump has grown increasingly frustrated with the governor and has joined Cruz in calling for Kasich to end his campaign. Kasich cast Trump's focus on him as a sign that he's best positioned to win over the businessman's supporters.

"They're not really his people," Kasich said. "They're Americans who are worried about, they're really most worried about their kids, are their kids going to have a good life?"

If Cruz wins all of Wisconsin's 42 delegates, Trump would need to win 57 percent of those remaining to clinch the GOP nomination before the convention. So far, Trump has won 48 percent of the delegates awarded.

To win a prolonged convention fight, a candidate would need support from the individuals selected as delegates. The prolonged process of selecting those delegates would test the mettle of Trump's slim campaign operation.

Cruz prevailed in an early organizational test in North Dakota, scooping up endorsements from delegates who were selected at the party's state convention over the weekend. While all 28 of the state's delegates go to the national convention as free agents, 10 said in interviews that they were committed to Cruz. None has so far endorsed Trump.

Among Democrats, Clinton has 1,243 delegates to Sanders' 980 based on primaries and caucuses. When including superdelegates, or party officials who can back any candidate, Clinton holds an even wider lead -- 1,712 to Sanders' 1,011. It takes 2,383 delegates to win the Democratic nomination.

Sanders would need to win 67 percent of the remaining delegates and uncommitted superdelegates to catch up to Clinton. So far, he's only winning 37 percent.

Even if Sanders wins in Wisconsin, he's unlikely to gain much ground. Because Democrats award delegates proportionally, a narrow victory by either candidate on Tuesday would mean that both Sanders and Clinton would get a similar number of delegates.
