Provided she wins her dreadful party's nomination, of course she can win the presidential election and IMO it'll take star power to defeat her.
Perusing over at the DUmmies, there are a LOT of people who don't like her. Her detractors consider her in the pockets of corporate America, a big sin if you want to hold the Rat banner. The question is, if she gets the nomination, will more of her party's voters swallow hard and vote for her anyway, than will have to do the same over on our side? We don't have anybody yet who most people can accept, let alone get excited by.
Obama does have star power, even if it is only the sort of meaningless media adulation that they shower on naughty celebrities. I'm hoping that he becomes the anti-Hillary, the rest fade away quickly, and she defeats him only after getting very nasty and dirty. With the eventual Republican nominee most likely being someone that the majority of the conservatives are not going to like, we need far more pissed off Rat voters willing to go third party in November, 2008, than will stay home and not vote for a McCain or Giuliani.
