Watch: Everyone Told Trump A Wall Wouldn’t Work. After This, They’ll Be Apologizing

Donald Trump has maintained front-runner status since shortly after announcing his White House ambitions this summer. Much of that success has been attributed to his firm stance – even prior to entering the Republican primary race – on immigration reform, including the construction of a comprehensive border fence.

This past winter, Trump told an audience in Iowa that, should he eventually become president, he would “certainly start by building a very, very powerful border.”

While such rhetoric has earned him substantial support among Republicans, his critics have dismissed him as naïve or even xenophobic. With the success one Arizona town has had with its fence, however, Trump and his supporters have some evidence to back up claims that a larger-scale border wall could be effective.

Along with a fence on the Mexican side of the border, Yuma finalized construction of two additional fences in the U.S. to create a barrier few immigrants can cross. Border Patrol agents including Richard Withers boast that the Yuma sector is the most secure of the entire border.

Yes, the feds can build a fence that works and Yuma is proof https://t.co/fFeHwcgxNJ

Sector chief Anthony Porvaznik agrees.

“We essentially apprehend 92 percent of all entries through the Yuma sector,” he said. “That is 126 miles of border, which includes 12 miles of these sand dunes. On a scale of 1 to 10, we are a 9.”
