On the up side, Bush seems to have become the President no one cares about. The 9/11 wrrrr on trrrr has run out of rhetorical steam, and no matter how much he bobs and smirks and flaps his arms around, no one is paying attention any more.
I don't expect he'll stand trial for anything much, even though people are still dying pointlessly. But if Obama wins there may be some constitutional changes which will make an outbreak of Chimp 2.0 a little less likely.
I suppose Bush could still try to do the Iran thing as a final parting fuck you, but I think he'd run into a solid wall of WTF from pretty much everyone if he tried that. Cheney will still be masturbating over pictures of fall-out patterns, but the chances of the happy explosion he's so desperate for are looking increasingly remote.
We may have to console ourselves with the thought that when Cheney leaves he'll very likely be thinking of himself as a failure - because he didn't make the president emperor of everything, and because Iran will still have people living in it who aren't radioactive and dead.
Which is going to be small beer, but better than nothing.
Chimpy will go back to his usual lettuce-like level of sentience on the speaking circuit. He'll be invited to events where no one is going to care what he has to say, so he'll finally have the uncritical adoring audiences he's always wanted - and would have had much earlier, if it hadn't been for those pesky Democratics.
I mean the factions of the party backing each one, not the actual candidates themselves. Conservatives want live babies so they can raise them to be dead soldiers. - George Carlin
But Cheney can't win this - because if someone else does it, it just won't feel the same.
