I think that is a false assuption on Deans behalf. If the Democrats had a major landslide victory in 2006 as the Republicans did in 1994, then I could agree that the Democrats were actually elected to end the war. However, many of the seats lost by Republicans were due to incumbants self-destructing during their own terms rather than a national tidal change.
Oh my God, how can you still be in denial about last year? The Allen vs. Webb race was not the entire election. How do you explain the Democratic landslides in Indiana and New Hampshire? There were no major gaffes there. There was a 6 seat pick-up in the Senate, 30+ in the House and both switched control! If thats not a national tidal wave I don't know what is.
