From Byron’s latest:

you know the Giuliani campaign — the campaign that was the national frontrunner for nearly all of 2007 — is in trouble when Giuliani seeks to define himself, not by his own record, but by the two frontrunners here in Florida, John McCain and Mitt Romney. You don’t like Candidate Number One or Candidate Number Two? Well, give me a try! And you really know the campaign is in trouble when Giuliani, the archetypal man-in-charge with an extraordinary record of accomplishment in New York City, morphs into the John Edwards of the GOP race, tut-tutting the bickering between the two leaders. But that’s the way things are going for the mayor here in Florida.
