Obama probably, but I'm not totally sure.
Who knows what they'll be able to dig up on him though. They're not going to find anything new on Hillary that we don't already know. Her approval isn't going to get any worse, it can only go up. Obama's could still go down.
Yeah. Hillary is this election's Bush in 2004. She is divisive and unpopular, but is well known. She also has a stereotypical culture of about 25% of the population's goal in life is to have her in the White House. Her objective should be to smear the hell out of the other guy. She must show that her opponent is unacceptable and she will win. That will be a sinch with everyone except for maybe McCain and even he created some pitfalls for himself. He can be shown as the guy who is popular because he says what you want him to say while Hillary can say that she is divisive because she has a strong, clear plan.
she also has the establishment behind her, as did Bush. Both are very polarizing, and both will/did raise record amounts of money. it will be tough to beat her. even though obama is polling well in iowa and new hampshire, clinton still leads florida by over 30%. obama will need to win both iowa and new hampshire to have any hope, and even then she may still win.
