I've read several predictions for the House elections in 2010 and they seem to ignore the fact that the Republicans are making asses of themselves and alienating the woman/black/hispanic/miscellaneous vote.
The only predictions I have seen are the GOP gaining 5 to 10 seats from some of the Highly GOP territory they lost like ID-01, CO-04, MS-01, VA-05, NM seat held by Pearce(Hispanics would be important here.) and maybe 1 or 2 suprises like ME-01.
MS-01, NM-02 are actually both more than a little unlikely unless we get something of a wave rebound (in which case both are goners). CO-4 and VA-5 depend on how their new Reps settle in and who challenges them, but are definitely not to be ruled out at any point unless we're past the primary and the opposition is 3rd tier. There are some more seats of similar calibre (AL-02 anyone?)
Walt Minnick is on borrowed time and his best bet would probably be a rematch against Sali... which is certainly not off the cards.
I'd look closer at recently lost suburban seats, frankly. Rural seats have a way of sticking with Representatives they like.
