Sen. Patty Murray, D-Wash., chairwoman of the Democratic Senatorial Campaign Committee, supports raising taxes on all Americans in January 2013 from levels that have been in effect for more than a decade. She came right out and said so in a major speech at the Brookings Institution, a center-left think tank, on Monday.

“So if we can’t get a good deal — a balanced deal that calls on the wealthy to pay their fair share — then I will absolutely continue this debate into 2013, rather than lock in a long-term deal this year that throws middle-class families under the bus,” she declared. “And I think my party, and the American people, will support that.”
