Did Rick Perry really think that he could trip up Romney by talking about the aliens who worked at his house? In a debate on Nov. 28, 2007, Giuliani went after Romney on the very same issue. Romney had seen this one coming for four years, so it’s no surprise that he had an answer ready. Perry might have been able to hurt Romney with an effective follow-up, but instead he hurt himself with the interruptions. He didn’t look tough, just rude.
