Bush isn't running. People are going to be voting in local races and for their congress-critters. Congress-critters have a 98% re-election rate. Nothing that you mentioned is a show-stopper in a congressional race, since it wasn't the congress that did it.
In other words, not enough people care for any of it to make a difference.
While I disagree with PD on us picking up 5 seats in the Senate, I seriously doubt that we are going to lose seats in either house. Republicans will still vote Republican, Democrats will still vote Democrat, and Independants will still vote with their wallet. Their wallets are more full now than they were two years ago. QED.
