Deroy Murdock: Walls work. Democrats know this but they want Trump to fail

Of all the Democrats’ arguments against a southern border wall, the shadiest is that it would not work.
According to House Speaker Nancy Pelosi, D., Calif., President Trump is “forcing American taxpayers to waste billions of dollars on an expensive and ineffective wall.” As he joined Pelosi in rebutting the president’s January 8 Oval Office address, Senate Democratic leader Chuck Schumer of New York decried Trump’s “ineffective, unnecessary border wall.” Schumer added: “We can secure our border without an expensive, ineffective wall.”
In fact, walls work. Love them or hate them, their effectiveness is indisputable.
AS TRUMP MAKES BORDER WALL PITCH, OTHER COUNTRIES SAY THEIRS WORK
• “Part of our area is covered with some fencing on our east side. That accounts for about 6 percent of our traffic,” Border Patrol chief Raul Ortiz told journalists during President Trump’s January 10 visit to Rio Grande Valley, Texas. “Where we have no fencing, over 90 percent of our traffic occurs in those areas.” A day earlier, Ortiz added, 450 people were apprehended in the unfenced sector, including 133 from such non-Latin nations as India, Pakistan, and Romania.
• Some 560,000 illegals were caught astride San Diego and Tijuana in Fiscal Year 1992, when a border wall was installed there. By FY 2017, the Border Patrol says it snared 26,086 — down 95.3 percent.
