Last month, 60 Members of the House of Representatives, including 51 Democrats, voted against the war supplemental for Afghanistan, Pakistan, and Iraq. But this week, when the House is expected to consider the agreement of a House-Senate conference on the war funding, the supplemental could well be defeated on the floor of the House - if most of the 51 anti-war Democrats stick to their no vote - which they might, if they hear from their constituents.
The key thing that's changed is the Treasury Department's insistence that the war supplemental include a $100 billion bailout for the International Monetary Fund - a bailout for European banks facing big losses in Eastern Europe, the international version of the Wall Street bailout.
House Republicans, including Minority Leader John Boehner, have threatened to vote no on the war funding if the IMF money is attached. If Boehner could bring all the Republicans with him, and if all the Democrats who voted no last month voted no again, the war supplemental would fail on the floor of the House, 200-228.
But not every Democrat who voted no before will vote no now, and therein lies the drama. The House leadership didn't need those anti-war Democrats before, so in a way it was a "free vote" - 51 Democrats could vote on behalf of their anti-war constituents without running afoul of the leadership. But if Treasury insists on the IMF money, and Republicans vote no, the leadership will need 18 of those Democrats now.
