SAY at least this for the Democrats: They are beginning to find the courage of their profoundly mistaken convictions. They have moved from pretending that a nonbinding resolution against sending additional troops into Baghdad and Anbar Province is a serious blow against the war in Iraq to more strenuous attempts to handicap the prosecution of our fight there.

The House Appropriations Committee is set to take up a bill that would authorize $120 billion in additional spending to cover--among other things--the Iraq surge. Speaker Pelosi has known all along that refusing to fund the surge would be a political mistake, since it would open her Democrats to charges of defunding troops in the field. At the same time, her liberal base--and much of her House majority--wants the war stopped, now. The bill tries to keep them happy by setting deadlines for troop withdrawals. President Bush would be told to certify in July, and then again in October, that the Iraqi government had met certain political and military benchmarks. The bill calls for withdrawing U.S. troops within 180 days if these benchmarks aren't met (although Bush could waive them), and by September of 2008 no matter what. Senate Democrats, meanwhile, are working on a resolution that would call for withdrawal by March of 2008.
