best line from today's Republican Pres. debate

I didn't even know that there was supposed to be a Republican Presidential debate today, but I turned on the ABC "This Week" show this morning and there it was. I am definitely a Rudy Giuliani supporter, but I must say that Mitt Romney had the best line in the debate when he noted that Barak Obama had gone from saying he'd meet with our biggest enemies without pre-conditions to saying we should invade Pakistan and Romney said: "He's gone from being Jane Fonda to Dr. Strangelove all within a week." That was awesome.
