If Huckabee gets nominated, the Democrats will win the election in 2008, simply because Huckabee will not be able to bring over independents, cause he will be the religious right candidate if he takes the nomination. He doesn't believe in evolution and that will rally the right wing of the party, but will probably turn off all moderates for pulling for a republican, and independents usually decide elections.

The problem with the democrats and why they always lose is that they put up candidates who try to appeal the looney lefties, like Dukakis, Mondale, and McGovern, and forget about the center. The republicans usually win cause they put a candidate who is appeals to the religious right, but is able to not be perceived as a right winger, and that is tough to do. We can debate what George W. Bush REALLY believes in, but in 2000, he was able to please the rightwing in the primary, and then run as a compassionate conservative to win the election......well win the Electorial College

Politics is all about perception and how you sell yourself, and unfortunately issues usually come in second to how the candidate presents himself.
