This is not the conventional wisdom, but I think you can make a good case for it. Hillary is divisive and has very high negatives. Obama is clearly very inexperienced, and he has gotten a total free pass so far from the media and his opponents. A few ads with him next to his black racist pastor and Loius Farrakhan and a lot of people will think twice about voting for him. That said, I watched McCain on Hannity last night and he was terrible. He looked stiff and defensive and kept blabbering the same crap from the debates. He is not going to get too many republicans charged up for the campaign.
When the republican party goes nuts with this black church of obama's during the election, obama's campaign and it's backers will of course scream "racism, racism", but their cries will get not traction at all because anyone with a brain can see the republican charges are authentic and accurate. This ain't goin away.
