I remember seeing Guiliani explaining in an interview the problem with sex business's on Times Square and 42nd Street. Up to that point I had taken a very libertarian view of such things. I have never heard an argument on any issue explained in such simple and persuasive terms.
I don't believe that any politician on either side can match Guiliani in a debate format.
Can you just see the unstable McCain debating him? What a laugh that's gonna be.
