If Guliani or McCain decide to get into the race, they'll be hard to beat. They can lose some Republicans because they'll pick up a lot of moderates and even some Dems.
I don't see Guiliani going anywhere, although I do think it is possible that he may be tapped as the running mate if Hitlery DOES NOT get the 'Rat nomination (he could probably deliver NY). I have always wondered if there is an agreement between Bush and McCain to support McCain in 2008, but Bush's poll numbers could make that a moot point.
Don't expect the Dems to be foolish enough to crossover for anyone in 2008. They want the presidency too desperately to sacrifice it.
All a Giuliani or McCain nomination would do is cost the GOP votes.

Last I checked, independants and Dems don't vote in Republican primaries. McInsane and Giulani are DOA.
