U.S. House Democrats say the White House’s tax compromise with Republicans is a bridge too far for them. On Thursday the Democratic caucus held a non-binding vote rejecting President Obama’s tax deal that would keep income tax rates where they’ve been for the better part of the past decade. The deal also would temporarily lower the payroll tax and extend unemployment benefits. The last shriek of a House Democratic majority that’s about to go poof, or a rallying cry for progressives and liberals throughout the land? If taxes go up on all Americans in January, the backwash against Democrats might be fearful. “A clear majority of the U.S. House of Representatives supports this plan,” Rep. Dan Boren, D-Muskogee, said in a statement. “We are allowing the liberal wing of the Democratic caucus to hold these critically needed tax cuts hostage.” Maybe, but not for long. Even if Speaker Nancy Pelosi and her loyalists fight it out on last stand hill, you’ve got to think the new Republican majority’s first agenda item will be taxes.
