Ooops, my bad. It didn't occur to me to post sources for something that was widely reported and discussed in the news all summer and fall. But I guess not everyone follows the news. Here ya go (here are a few references; there are lots more available):
"For months, much to the consternation of many of his fellow Republicans, Charles Grassley, the ranking minority member on the Senate Finance Committee, had continued to negotiate behind closed doors with chairman Max Baucus and four other members of the panel. No Republican received more TLC from Barack Obama, who has met with Grassley three times at the White House and called him three times more just to keep in touch. White House aides reckoned that if Grassley, with his conservative credentials, could find a health-care deal he liked, a significant number of other Republicans might be persuaded to climb aboard. 'Health care not only is 16% of the gross national product, but it touches the quality of life of every household as few others do,'" Grassley declared back in April. 'I'm doing everything I can to make the reform effort in Congress a bipartisan one.'"
"Senate Finance Committee Chairman Max Baucus (D-Mont.) worked for months to find common ground with Republicans on health care reform ..."
"The bipartisan Gang of Six, which has been meeting for months, could gather for the last time Monday as Baucus said he aims to wrap up the negotiations. The senators could indicate at that point whether they will sign onto the bill, Baucus said.
'We are starting to reach closure,' Baucus said after a rare Friday meeting of the group."
"Senate Finance Committee Chairman Max Baucus could lay out a health care reform plan as early as Saturday, the Montana senator told his colleagues on a Friday afternoon conference call. Baucus (D-Mont.) told the bipartisan group of Senate negotiators that has been working for months to craft a compromise that he will be releasing a plan soon, according to sources familiar with the call. ... The six negotiators on the committee are Baucus, ranking Republican Chuck Grassley (R-Iowa), Jeff Bingaman (D-NM), Kent Conrad (D-N.D.), Olympia Snowe (R-Maine) and Mike Enzi (R-Wyo.)."
"This is who is in the room helping Baucus put together his bill. Olympia Snowe, Mike Enzi, Chuck Grassley, Jeff Bingaman and Kent Conrad. In a Senate of 60 Democrats and 40 Republicans, the health-care reform bill is being written by three centrist Democrats, one centrist Republicans, and two conservative Republicans. And until last week, Orrin Hatch was in the room, too."
"Bipartisan health care negotiations resumed this morning among members of the Senate Finance Committee.
Three Republicans on that committee, ranking member Charles Grasley of Iowa, Olympia Snowe of Maine and Orrin Hatch of Utah have been working hard to find a common ground with Democrats on the committee. All three, currently in the Senate office of Finance Committee Chairman Max Baucus, D-Mont., agree that progress is being made, but it is unclear when they could emerge with a bipartisan bill. Grassley said this morning that a bipartisan bill could be presented this week if the non-partisan Congressional Budget Office (CBO) returns an acceptable cost estimate and Grassley, Snowe and Hatch all sign off on the policy proposals."
"The Finance Committee's "Gang of Six," a group of three Democratic and three Republican senators, has been working for months to craft bipartisan health-care legislation."
I did misspeak when I said none of the Republicans on the committee voted for the bill -- I forgot that Olympia Snowe did.
