I'm worried about the increasing anger in McCain rallies. I think that Obama realizes that crazed Repubs are a threat, which I think explains the fact that for the third day straight, Obama has not been campaigning anywhere.

I think he understands that he's pretty much won the election, so he's increasing his presence in ads, and decreasing it in public, so as not to take unnecessary risks.

Play it safe, Obama, we're worried about you.

PS though it could be that he's just preparing for the debate. What do you think?
