Last week, Herman Cain twice suggested that we should build an electrified fence along the border with Mexico that would kill anyone who touched it. On Sunday he reversed course, insisting he had just been joking, even though video of his remarks makes it pretty clear that he was perfectly serious. Today, he reversed course again, admitting that his original remarks weren't a joke at all.
This is a pretty obvious subject for tonight's Republican debate. You can see it coming a mile away and every candidate should have a pretty well-prepared response about it. Two questions, then. First: What do you think Herman Cain will say about this? Second: with plenty of time to prepare, what do you think Rick Perry will say about it? Will he be able to string together 30 seconds worth of coherent thoughts on the issue? Or will he screw up completely as he usually does?
