I like Clinton (heh) and Edwards.
Sadly, I don't think Obama is going to make it. Suprised he's not a top option here, though. I know Clinton has a barrier to overcome, being a woman, but I think Obama's got at least 3: race, age, religion. Kennedy was a rebel, being Catholic. And I can't say our country is where it should be on race issues. And besides, a man as young as he is doesn't seem to have as much credibility. Since younger voters typically don't show up, I think older voters won't be as excited by his youngness (comparatively).
I'm not a Clinton fan at all, but I do like and admire Edwards a lot, however Obama is my man.
I'd have to disagree with what you said about Obama making it. Let's not forget that we still have a lot of time left until the elections. Obama's campaign has electrified young voters, now will they vote? Well, we'll just have to wait and see. But as a regular poster on his "my.barackobama.com" I've seen firsthand the amount of college age students who are fully behind him.
I don't understand why religion would be an issue. He's a Christian and goes to a Christian church, just like the other candidates. If you're referring to the huge misreporting by Fox News that he's a muslim, it's not true.
I also don't see race as an issue. His biggest supporters are white, infact it may just be an issue among black voters who honestly don't quite see him as being black enough. However I think once many of them really get to see where he stands on the issues they will support him.
As far as age, I would say that wouldn't hurt him as much as "inexperience". I think people would like to have a candidate who has some youth. I mean if John McCain got the nomination he would be 72 before he took office, I don't know about most people, but that would be an issue with me. However I don't think he's any less experienced than anyone else. I realize he hasn't been in the Senate for a full term, but at least he has some federal government experience, where as Rudy Guiliani does not. His claim to fame is being mayor of New York City during 9-11.
I also think we're going to be in for a surprise when the Obama campaign releases his fundraising numbers for the first quarter. Most experts believe that they must've raised a significant amount (possibly more than Hillary's 26 million) because they're holding off on releasing it. He did get over 20,000 more people to donate to his campaign than Hillary did, so that is significant, especially since people who have already donated are more likely to donate again.
ETA: Obama did keep up with Hillary's pace, raising $25 million dollars, which 23.5 of that can be used for the primaries, whereas only 20 million of Hillary's can be. He also had over double the amount of donors Hillary did, many of which were online and most of which gave a very minimum amount of money, meaning they can keep donating. A lot of Hillary's donors gave the maximum, or at least close to the maximum.
