The big gains the GOP made last night they'll be able they'll be able to keep in 2012 for a couple of reasons. First, unless the economy improves, the President will have a difficult time carrying any Democrats on his coattails. Second, GOP state legislators and governors will be able to redraw congressional districts to protect vulnerable new members and promote GOP challengers who fell just short. Meanwhile, Democrats will be made to run against one another and decrease their strength. For example, in MI CD 9, Gary Peters, the apparent winner, will almost certainly be the target of GOP redistricting and he'll find more Republicans voting in his district. I wouldn't be terribly surprised if the GOP holds onto their large gains and even adds a couple of seats in 2012.
