At this point I think the republicans can win the house and senate back but may as well write the white house off.
Absoluitely no chance in hell. The Dems will widen the margin in both. The Dems are playing the game until the '08 election- NO major mis-steps, no huge controversial initiatives (like Hillary-care), nothing... With the MSM providing a tail-wind, there's absolutely no way I can see us re-taking either chamber, and the White House is looking really bleak as well.
