Donald Trump famously wants to build a wall on our southern border and stick Mexico with the tab, but Scott Walker is looking to our northern border with Canada—which the AP notes is the world's longest at 5,525 miles—and says that he'd be open to putting up a wall there. "That is a legitimate issue for us to look at," he tells Meet the Press today, per the Hill. "Some people have asked us about that in New Hampshire. They raised some very legitimate concerns, including some law enforcement folks that brought that up to me. I think we need to secure borders in general." Walker goes on to add that it's not "just about building a wall and securing borders," but also "making sure our intelligence community has the ability for counterterrorism and the ability to go after the infrastructure they need to protect us."
The rhetoric could be part of a new aggressive approach that Walker, who is currently slumping in the polls, was reportedly feeling out earlier this month. Meanwhile, Chris Christie told a town hall in New Hampshire yesterday that he wants to track immigrants like FedEx packages. "At any moment, FedEx can tell you where that package is. It's on the truck. It’s at the station. It's on the airplane," Christie said, via ABC News. "Yet we let people come to this country with visas, and the minute they come in, we lose track of them. We need to have a system that tracks you from the moment you come in, and then when your time is up, we go get you and tap you on the shoulder and say, 'Excuse me, thanks for coming, time to go.'"
