In an epic struggle settled at dawn, the Democratic-controlled Senate passed health care legislation Thursday, a triumph for President Barack Obama that clears the way for compromise talks with the House on a bill to reduce the ranks of the uninsured and rein in the insurance industry.

The vote was 60-39, strictly along party lines, one day after Democrats succeeded in crushing a filibuster by Republicans eager _ yet unable _ to inflict a year-end political defeat on the White House.

At the White House, Obama called the vote historic, and said because of it, "we are incredibly close to making health insurance reform a reality in this country. Our challenge now is to finish the job."

Democrats, led by Majority Leader Harry Reid of Nevada, said they would, by early in the new year. Even before they held a celebratory news conference, Speaker Nancy Pelosi issued a statement pledging, "We will soon produce a final bill that is founded on the core principles of health insurance reform: affordability for the middle class, security for our seniors, responsibility to our children by reducing the deficit, and accountability for the insurance industry."

The House passed its bill in November, and officials said it was likely to be February before the two sides can sort out their differences over issues as diverse as government's role in a remade health care system, coverage for abortion and federal subsidies for lower and middle-income families who would be required to purchase insurance.

Senate Republican attacked the bill to the end, and citing public opinion polls, said they would use it as an issue in the 2010 congressional elections. "This debate was supposed to produce a bill that reformed health care in America. Instead, we're left with party-line votes in the middle of the night, a couple of sweetheart deals to get it over the finish line, and a public that's outraged," said the Republican leader, Sen. Mitch McConnell, R-Ky.

The Senate vote unfolded as the sun rose over the Capitol on the day before Christmas, and marked the culmination of a battle that lasted months and included failed bipartisan negotiations, a last-minute flurry of Democratic dealmaking to lock in 60 votes and a highly partisan debate that held lawmakers in session a near-record 25 consecutive days.

For the third time since Sunday night, Sen. Robert C. Byrd of West Virginia, 92, was wheeled into the Senate so he could cast his vote. Sen. Jim Bunning, R-Ky., did not vote.
