For what it's worth, one of Rudy Giuliani's bigger applause lines Tuesday in Henniker followed his call for tamper-proof ID cards for everyone coming into the United States. I don't have the exact quote, but he said, in effect, the country needs to know who you are and why you're here, and if you don't want to come forward, then you should be thrown out [applause].
