That being said, the crazies (some of whom are going to be elected) can only run in circles, hold hearings and look foolish. The Senate will NOT have enough idiots to pass stupid stuff, and Obama is unlikely to sign it if they did.
The Republicans spent the last 2 years refusing to cooperate on almost ANY reasonable legislation, and there will not be enough of a power shift to allow them to run rough-shod over the Democrats.
Sadly, what it may lead to is gridlock....with very little of ANY significant stuff being passed.
