Incorrect. Cain and Romney have also said they'd build the fence. You must have missed Cain's joke, or whatever about an "electric fence". Probably Santorum also. Not sure where Newt is on the fence, but he's very weak on what to do with the illegals already here.
Mitt we already knows says whatever it takes to get elected and Cain backtracked the very next day and said he was joking and a week later is touting Perry's plan (but calling it his own).
I have heard that Perry's plan came from his visits to Israel and patterned after their border system.
Perry is just doing what he said he was going to do and give America a good dose of honesty. We can take it or leave it but I promise you this, by 2020, no matter who gets elected we will not have a full border fence. The question is will we have a secure border or is everything just campaign rhetoric. I already know Perry has put his and my money where his mouth is for at least the last 6-7 years.
