Led by Pelosi, the House Democrats did not back Obama’s tax compromise bill.

In a raucous, closed-door meeting on Capitol Hill, mutinous Democrats chanted: “Just say no!” as they vowed to overhaul Obama’s plan to extend lower tax rates for nearly all Americans, according to lawmakers in the room.

It is different in the Senate. Legislation aimed at avoiding sweeping tax increases looks headed for Senate approval after negotiators added sweeteners to promote ethanol and other alternative energies.

Tax provisions designed to increase production of hybrid cars, bio-diesel fuel, energy-efficient homes, coal and energy-efficient household appliances would be extended through the end of 2011.

Senate Majority Leader Harry Reid set the vote for Monday at 3 p.m. (2000 GMT).

Obama said on Thursday he expected the agreement would eventually pass, for the simple reason that should the House balk, the Republican House in three short weeks, will pass anyway. And that bill, the one in January, will be stripped of all its sweeteners.
