The fence

'When I'm in charge of the fence, we going to have a fence. It's going to be 20 feet high. It's going to have barbed wire on the top. It's going to be electrocuted, electrified. And there's going to be a sign on the other side that says it will kill you.' — Cain, Oct. 15, 2011, talking about the United States-Mexico border at a rally in Tennessee. A day later, he called the proposal a joke.
