The House Democrats are working on a bill to force withdrawal from Iraq by the end of 2008 or, if Iraq is not cooperative, a year earlier. But their efforts are clearly going to produce a one-chamber bill. Not only can't the Democrats pass it in the Senate, but they can't even really propose it without risking the loss of Sen. Joseph Lieberman, a supporter of the war, from their Senate majority.
What may eventuate is a stalemate where the House refuses to fund the war without its amendment and the Senate and/or the President want the funding without the restrictive amendment. In such a contest of wills, the Republicans will win because the House won't want to be in the position of voting against funding troops in the field. In this game of chicken, the side that is willing to go to the mat will win. The Republicans are. The Democrats aren't.
