I was born and raised in the South and my family is still there. It is in the South that Guiliani is drawing some of his biggest and most enthusiastic crowds. They have a sense of humor in the South as well as concern about who could fight our enemies most effectively.
There will be no clear winner from the Primary races so I don't expect to see anyone dropping out. It appears likely that the nominee will come from the Convention not the primaries and Guiliani will likely go into it with more delegates than any of the others. He will win half the Southern primaries.
What you think is "enthusiastic" is simply pandering to friendly crowds in urban cities -- (the destestable) McCain, Huckabee & Bayh could claim the same thing -- which doesn't count for jack state-wide on Election Day, and you know that to be a fact if you were raised in the South, which I doubt.
Like I said, bookmark this thread so I can rub your face in it in late March, 2008, after Guiliani tearfully wipes away his end-of-campign tears with his evening gloves.
