Some lawmakers used the moment to appeal for a new tone in the discussion of the volatile issue. “Let us stop the shouting and name calling and have a civilized debate on health care reform which I hope, when legislation has been signed into law, will bear his name for his commitment to insuring the health of every American,” Senator Robert C. Byrd, Democrat of West Virginia, said in a statement on Mr. Kennedy’s death.  Some, however, expressed little hope for a permanent cease-fire. “We’ll pause out of respect for our fallen comrade, but nothing seems to have any effect on the partisanship,” said Senator Arlen Specter of Pennsylvania, who recently switched parties and became a Democrat.  Whether the loss of health reform’s longtime champion will substantially alter the dynamic or the outcome of the Congressional fight will be determined only when Congress returns in September. Mr. Kennedy’s colleagues said they hoped his example would provide new inspiration.  “Maybe Teddy’s passing will remind people once again that we are there to get a job done as he would do,” said Senator Christopher J. Dodd, the Connecticut Democrat and close friend of Mr. Kennedy who filled in for him as chairman of the Health, Education, Labor and Pensions Committee.  Republicans said they did not ultimately expect much change in the health debate.  “Democrats will rally, but they still have to come up with a bill that works,” said one senior Republican official who did not want to be identified when talking about the delicate subject of how Mr. Kennedy’s death would play out in the policy fight. Another top Republican said the fight was already somewhat suspended with President Obama on vacation and would most likely “pick up right where we left off in a week or two.”  Republicans also noted that Mr. Kennedy, though an ideological liberal, was a legislative pragmatist who worked with Republicans to strike compromises on difficult subjects like health care, education and immigration. They said they saw little such reaching across the aisle in his absence.  Several Republicans also said they believed Congress would be closer to a health deal than it is now if Mr. Kennedy had regularly been on hand in the Senate, working face-to-face with his colleagues and using his prestige and credibility to advance the issue.  In a recent interview, Senator Orrin G. Hatch, Republican of Utah, said Mr. Kennedy was “the only Democrat who could really move all the Democrats’ special interests into coming along” with a bipartisan approach. Mr. Hatch said that in his absence, Mr. Kennedy’s staff members had written a “one-sided, partisan bill,” approved by the health committee on July 15. But Democrats say Mr. Kennedy had been deeply involved in putting together the legislation, had been consulted regularly on even the fine points and had been elated when the health committee approved its measure.  “He felt confident that we were on track even though there is a lot of ranting and raving going on right now,” Mr. Dodd said.  Howard Dean, the former presidential contender and national Democratic chairman, said it was “conjecture” to imagine how the course of health legislation might have changed had Mr. Kennedy lived. But, he said, “his death absolutely will stiffen the spine of the Democrats to get something this year for this extraordinary giant in Senate history.”  Other Democrats and health care advocates said they also viewed enacting health care legislation as the best tribute they could pay to the senator who had pursued accessible health coverage for every American for decades.  “Ted Kennedy’s dream of quality health care for all Americans will be made real this year because of his leadership and his inspiration,” Speaker Nancy Pelosi said.  In the most concrete effect of Mr. Kennedy’s death on Capitol Hill, the Democratic majority in the Senate will be reduced to 59 for at least the coming weeks, since Massachusetts law requires a special election to fill the seat and one might not be held until early next year. But Senate Democrats had for weeks accepted the fact that Mr. Kennedy would not be able to return to the floor even for a critical filibuster-breaking vote.  With only 59 seats, the Democrats are one short of the number they need to overcome procedural tactics that prevent a vote; if they face a filibuster, the leadership would have to hold its own members together and attract at least one Republican supporter beyond that. The math may lead Democrats to look more closely at considering health care under a procedural shortcut that could avert filibusters but also leave them with a health plan far reduced in scope.  The White House declined to comment Wednesday about what impact — if any — Mr. Kennedy’s death would have on the health care debate. Mr. Obama did not mention the health care debate in a written statement about Mr. Kennedy’s death or in brief televised remarks delivered from Martha’s Vineyard on Wednesday morning. He did, however, recall the bipartisan manner in which Mr. Kennedy often approached legislative fights.  “He could passionately battle others, and do so peerlessly, on the Senate floor for the causes that he held dear, and yet still maintain warm friendships across party lines,” Mr. Obama said.

The death of Senator Edward M. Kennedy became a rallying point for advocates of health care reform and could provide a new tone in the debate.
