Chris Christie said Saturday that if elected president, he will track immigrants who overstay their visas like FedEx packages.

"I'm going to have Fred Smith, the founder of FedEx, come work for the government for three months. Just come for three months to Immigration and Customs Enforcement and show these people," the New Jersey governor said at a town hall event here.

Christie added that while FedEx can track boxes, the U.S. can't track undocumented immigrants.

"You go online and at any moment, FedEx can tell you where that package is," he said. "Yet we let people come into this country with visas, and the minute they come in, we lose track of them."

Christie added, "We need to have a system that tracks you from the moment you come in and then when your time is up," he said. "However long your visa is, then we go get you and tap you on the shoulder and say, 'Excuse me, it's time to go.'" – CNN Politics, Aug. 31, 2015

The presidential race is already entering silly season. Wisconsin Gov. Scott Walker wants to build a wall spanning the U.S.–Canada border. Do we have a problem with Canadians sneaking into the United States to take our coffee and donuts? No, of course not. Canadian people have Tim Horton's. They do not need our pale imitations.

New Jersey Gov. Chris Christie has an even wackier idea. He starts out correctly by recognizing visa overstays are a bigger problem than people crossing undefended borders. His solution, however, is no more practical than Walker's Great Wall of Wisconsin.

Christie notes that FedEx can track boxes better than the U.S. tracks immigrants. A normal person would say this is obvious. Packages are inanimate objects that stay in direct FedEx custody 24/7 until delivery, while immigrants are human beings and not so easily corralled.

Christie is not a normal person. He observes bar codes and scanners at every stage of the journey working for FedEx, and presumes they will suffice to track immigrants, too. It's obvious. He'll bring in Fred Smith to straighten out those clueless bureaucrats. It will take only three months.
