I've given money to the Dean campaign, because he elected not to take federal matching funds, but I think I like John Edwards in the national run. He seems more charismatic and holds populist positions very well. Edwards has a little baggage in a Senate Investigation of certain campaign contributions, and the fact that he's a trial lawyer might not be great for an already litigious nation, but I'd be willing to support him. Also, unlike Lieberman in 2000, he's not seeking re-election for his senate seat, in order to focus on his campaign. Again, I respect that a lot.
Dean is covered by the press in much the same way Al Gore was - yes, he does run his mouth somewhat, but a lot of it is blown out of proportion and misrepresented. I like the fact that he's a learned man - a doctor, and that he's unabashedly left-of-center. I'm not a big fan of the blogforamerica crowd, the group of people who are acting like Dean is the only viable Democrat running (perhaps because he is the biggest antiwar candidate, something the other candidates besides Kucinich cautiously supported) but I respect the fact that he's reached out through the internet like no other candidate and will actually directly respond to forum messages and the like. That level of access is a thrilling thing to have.
Wes Clark I have a high opinion of. It was his military organization that won wars in Bosnia, Afghanistan and Iraq, and he spent the summer of 2001 trying to speak to the "president" about potential terrorist threats. Not only that, he's extremely well spoken, another learned man whose command of language makes Bush's (noo-yoo-lar) malaprops seem even worse than usual. The biggest problem is his inexperience in actual government and with policy issues. I've heard him in interviews, saying things like "I don't know enough about that to comment right now, but next time I speak to you, I promise that I will", which is something I respect even more - he's not talking out his ass and hoping no one calls him on it (Gore did that several times to Bush during 2000 presidential debates). *My* biggest problem is that he doesn't have much credibility as a democrat, which is a little bit off-putting. I think he'd make a great Secretary of State (hell, give the job back to Powell, I'm sure he could do a better job if he weren't competing with Wolfowitz and Rumsfeld) or VP, if he doesn't get the nomination.
Lieberman - He frightens me. Strict orthodox Jew (won't work or ride in a car on the sabbath...) , wants to censor movies, actively pro-war. If this guy were a republican, I'd say he's one of the better ones, but he's a rightist dem.
Sharpton - No way in hell he'll even win a state. I guess he's this year's Alan Keyes. But... have you heard him speak? Slick as can be, radiates charisma, and his issues are a little different from Dean's, so he adds something to the debate among a bunch of talking heads arguing about how much they hate the war.
Kucinich - The leftmost of the candidates. I'm interested in seeing how well he does, even though I know he won't win any states. I hope he stays in the running for awhile though.
Gephardt - Is a centrist. Pro-war, but has tons of union support. He's a well known politician, but he's kind-of damaged goods to me, since as house minority leader, he couldn't keep members of his own party united enough to be a useful force against republican legislation. I'm sure he's got good connections but I think the party could do better.
Kerry - The vanilla candidate. Hasn't done anything to distinguish himself to me.
