I'd say no. Seriously think about it...logically, not emotionally. Hillary isn't going to get elected. She's too polarizing. And you think Howard Dean committed political suicide with "ARRRRRRGGGGHHHH!!!!", just wait till you hear "Hillary's ever-changing accent" over, and over, and over. It'll be used to emphasize her pandering. Obama. Sorry. Not going to happen. He's too junior to the Beltway.
So people many in here have questioned as even having the ability to get nominated have financial woes. Fred Thompson is starting to have a handful of nepotism allegations brought against him. Newt's talking smack, but I don't think he's electable either.
Personally, I think Bloomberg is going to be a late entry. And he has his own war chest.
On the Dems side, it wouldn't surprise me at all to see Gore make a run for it. He's making enough money off his books and so called documentaries to make a go of it. Heck, he may even be able to enlist the help of Edwards.
