Well, it's not a majority, and not veto proof, but 70 stalwart antiwar Democrats in the House (and Ron Paul, the liberatarian Republican from Texas) say that no matter what, they won't vote to extend the war in Iraq. (The current funding, of course, runs out on Sept. 30, 2007.) From a letter to Bush:

We are writing to inform you that we will only support appropriating additional funds for U.S. military operations in Iraq during Fiscal Year 2008 and beyond for the protection and safe redeployment of all our troops out of Iraq before you leave office.

The House takes up the Defense appropriations bill on July 25. Last week, only four House GOP members voted with Democrats to pass a timeable for withdrawal bill. Defense Secretary Gates met with the House Republicans this week, apparently convincing them to hang on until the Sept. 15 report on Iraq.
