His comments reflected a growing sense among Democrats that they may have to carry the legislation to expand coverage and try to control medical costs with votes from lawmakers of their own party — or at best a handful of Republicans.

Visiting economically stressed Indiana to announce $2.4 billion in taxpayer grants for electric cars and tens of thousands of jobs, Obama pledged successful conclusion of the health care overhaul that he argues would stabilize the nation's fiscal health.

"I promise you, we will pass reform by the end of this year because the American people need it," the president said.

That will take some doing, since action on legislation in the House and Senate has been slowed by divisive policy arguments. Republican leaders oppose the Democrats' approach, and they're saying Congress should start over. But in an interview after his speech, Obama said he is not wedded to a bill with Republican as well as Democratic support.

He said he is encouraged that a small group of three Democratic and three Republican senators on the Finance Committee continue to negotiate, but signaled impatience with protracted talks that haven't yet produced legislation.

"Sometime in September we're going to have to make an assessment" about whether to keep trying to negotiate with Republicans, he told MSNBC.

Obama said he "would prefer Republicans working with us" but that getting his main priorities for a health care overhaul are more important. It represents a marked change from the emphasis Obama placed on bipartisanship when he launched his campaign for a health care overhaul at a White House summit in March.
