How about another option? I'd classify myself in the "I'd vote for her (in the general election) and she might win." But I don't think she's a sure bet to get the nomination and if she does it's still to early to see if things are aligned in her favor.
Unlike most conservatives and even some strong liberals, I don't dislike her. I think she's a smart woman who I think would be qualified to serve as president if elected. With that being said, I think her strongest attribute to me is the person who she is married to. I've come to like Bill a lot, moreso in retrospect than how I felt when he was actually in power. And if Hillary gets in, I'm not going to lie--I'd be excited to see Bill Clinton back in the public spotlight and giving speeches on a regular basis. But keeping that all in mind, Hillary doesn't have the same energy and charisma that her husband is so good at, so she would be rather overshadowed by Bill's presence.
But if she's the nominee (which I think it is way to premature to proclaim at this time), I don't think I would have a problem voting for her. I don't see anyone in the Republican field who I think would be preferrable at this point. I had a decent amount of respect for McCain back in 2000 but since that he's come off as too much of a political opportunist for me to support. And I don't think he would have the whole-hearted support of Republicans, either. Guiliani--there's something about that guy that really irks me. I never bought into that whole "America's Mayor" deal--he always struck me as a shady egomaniac who I never found particularly inspiring. The guy has some major baggage to deal with, plus I don't think the Republican base will be all that enthused for him. I think the Republican's strongest candidate would probably be Mitt Romney--I think he has the most presidential-like presence and the widest appeal to his party. But with that being said, I would still vote Hillary over Romney based on where I lean.
Hillary's problems are going to be apathy amongst the Democratic base in the primaries, and widespread negativity from hardcore Republicans. Whether she can overcome either of these things remains to be seen. Personally, my preference as it stands right now is Edwards, with Obama second. Both of these candidates are more inspiring on their own merits and vision than Hillary. But I've got no real problem with the lady herself, and given the choice in the general election would probably vote for her, if mainly for her husband's sake.
