WASHINGTON -- Democratic congressional leaders are uniting around their last, best hope for salvaging President Barack Obama's sweeping health care overhaul.

Their plan is to pass the Senate bill with some changes to accommodate House Democrats, senior Democratic aides said Monday. Leaders will present the idea to the rank and file this week, but it's unclear that they will have the votes to move forward.

Last week's victory by Republican Scott Brown in Massachusetts cost Democrats the 60th vote they need to maintain undisputed control of the Senate, jeopardizing the outcome of the health care bill.

"We've put so much effort into this, so much hard work, and we were so close to doing some significant things. Now we have to find the political path that brings us out. And it's not easy," the No. 2 Senate Democrat, Dick Durbin of Illinois, said Monday.

The new strategy is as politically risky as it is bold. There is widespread support for Obama's goals of expanding coverage to nearly all Americans while trying to slow costs. But polls show the public is deeply skeptical of the Democratic bills.

Obama initially voiced doubts last week that a comprehensive bill was still viable, but he now seems to be pushing for it.

"I think the president believes that the circumstances that led him to undertake greater security for people in their health care ... existed last year, last week and this week," White House spokesman Robert Gibbs said.

House Speaker Nancy Pelosi, D-Calif., said last week she does not have the votes to pass the Senate bill without changes. Democratic congressional aides, speaking on condition of anonymity because the issue is in flux, said the latest strategy involves using a special budget procedure to revise the Senate bill.

The procedural route would allow a majority of 51 senators to amend their bill to address some of the major substantive concerns raised by the House. That would circumvent the need for a 60-vote majority to hold off Republican delaying tactics.

The remaining alternatives are unappealing: scaling back the health care bill to less controversial, smaller pieces, or setting it aside altogether.
