“There have been a lot of dumb ideas put out,” Paul said, speaking with Boston Herald Radio. “One that the Mexicans will pay for a wall, was probably the dumbest of dumb ideas. But putting a wall up between us and Canada is sort of a ridiculous notion. It is sort of like everybody is now competing to say, ‘Oh no, I’ll put them in camps. Oh no, I'll throw them out. Oh no, I’ll put everyone in jail. And I’ll have an electric fence, and I’ll do this.’ And it’s like, you know, the biggest thing we need to do is have a functioning immigration system, with a good work program.”
Paul is now polling at 1% support among Republican primary voters.
