Washington ? Well on the way to winning passage before Christmas after clearing its biggest hurdle in the wee hours of the morning, the Senate’s health care bill will make a “tremendous difference for families, for seniors, for businesses and for the country as a whole,” President Barack Obama said Monday.

Senate Democratic leaders basked in the victory for the landmark legislation that will insure 30 million more Americans. They looked ahead to the next make-or-break vote this morning. They snapped up a coveted endorsement from the American Medical Association and batted down Republican complaints about special deals lawmakers got in the bill.

“I don’t know if there’s a senator that doesn’t have something in this bill that was important to them, and if they don’t have something in it important to them, then it doesn’t speak well of them,” retorted Majority Leader Harry Reid, D-Nev., when questioned at a press conference about the GOP criticism.

The deals in the massive bill range from $100 million to pay the full cost of a Medicaid expansion in Nebraska, home to Democratic Sen. Ben Nelson, the crucial 60th vote for the bill, to exempting roughly 800,000 seniors in Florida from potential benefit cuts by private Medicare Advantage plans, something sought by Sen. Bill Nelson, D-Fla.

The American Medical Association got some special deals itself before declaring its support. A 5 percent tax on elective cosmetic surgery procedures was replaced with a 10 percent tax on indoor tanning services; a proposed fee on physicians to enroll in Medicare was dropped; and payment cuts to specialty and other physicians to pay for bonuses to primary care doctors in underserved areas were also eliminated, the AMA’s president-elect, Dr. Cecil B. Wilson, said.

“America has the best health care in the world — if you can get it,” Wilson said at a press conference with Reid and other leaders. “For far too many people access to care is out of reach because they lack insurance. This is not acceptable to physicians.”

Democrats prevailed 60-40 over Republican opposition early Monday, voting to block a threatened GOP filibuster of a last-minute package of Democratic amendments.

Democrats will have to put up 60 votes again this morning for a procedural vote on Reid’s underlying, 2,074-page bill. A last 60-vote hurdle awaits Wednesday, and final passage of the legislation — requiring a simple majority — is set for late Thursday, Christmas Eve, if Republicans take all the available time. As of Monday they said they would.

“I am willing to stay here. The flight that I have is Christmas morning, and I don’t plan on changing that reservation,” Sen. Bob Corker, R-Tenn., told reporters after a meeting of GOP senators. “We potentially are getting ready to pass a bill that there’s no question in my mind is going to lead to huge deficits down the road.”

With final passage on track, Republicans ramped up their criticism, denouncing the last-minute concessions that put the bill over the top.

“I am tired of the Congress thumbing their nose and flipping a bird to the American people,” Republican National Committee Chairman Michael Steele said in a conference call with reporters.
