I think Newt would be detrimental. Not because I don't like him. I do. But he would be so controversial that he might galvanize the independents and "Reagan Democrats" to make a left turn.
George Allen shows promise, but he needs to get the GOP behind him. There was another guy, can't remember his name, but he's a Republican governer somewhere that I had heard about and he sounded good. But again, if I can't even remember his name, he's not doing a good job of getting his message out.
Dave Markowitz, you are absolutely correct about the party getting its head out of its collective posterior, and not just at the presidential level. If the GOP members of Congress don't get it in gear and start taking the fight to the Democrats then we could lose Congress during the mid-term elections in the fall. This would ultimately give the Democrats even more momentum for 2008.
