And despite a 7% approval rating, 97% of congressmen were re-elected.

Wrong!
Republicans were seriously behind in the in the generic polls for congress in 2008, and proceeded to lose a big number of seats.
Right now, Republicans are steadily increasing their lead over the RATS in the generic congress polls, ergo Republicans win the House at least in 2010 if this continues.
