The New York Times reports it was House Speaker Nancy Pelosi who pushed President Obama to back comprehensive health care reform instead of a scaled back effort after Democrats lost their supermajority in the U.S. Senate in January.
"In a series of impassioned conversations, over the telephone and in the Oval Office, she conveyed her frustration to the president, according to four people familiar with the talks. If she and Harry Reid, the Senate Democratic leader, were going to stick out their necks for Mr. Obama's top legislative priority, Ms. Pelosi wanted assurances that the president would too. At the White House, aides to Mr. Obama say, he also wanted assurances; he needed to hear that the leaders could pass his far-reaching plan."
Said Pelosi: "We're in the majority. We'll never have a better majority in your presidency in numbers than we've got right now. We can make this work."
Politico also reports that it was Pelosi who "made it clear she would accept nothing short of a big-bang health care push" -- dismissing an "incrementalist" plan pushed by White House chief of staff Rahm Emanuel.
