Seriously one good reason not to vote for Obama. ?

Don't tell me about the so-called lack of experience because there have been PLENTY of other Presidents with even less experience who did just fine. Also during their run I didn't hear any of this strong opposition. I really hate to call everyone racists but I have yet to her one good argument I can't end in seconds. So just go ahead and say it's because he's black. Or are there really any good reasons. Clinton was going through a bunch of The Whitewater scandal and numerous allegations of affairs yet you all loved him. Obama has none of this. So what is the deal?
