If a candidate mentioned those things but said he was willing to quadruple the border patrol and ICE,set up hundreds of dedicated immigration courts for speedy deportations, and build enough detention centers to hold 10,000 at a time, and pay for it by taking from the Dept of Ed, Energy, HHS, and EPA budgets, then I'd vote for him.
But Perry's not saying that because he doesn't oppose the fence because it's a fence. He opposes it because he's a typical globalist, open border type.
