Why Is Gang of Six Deciding Health Care for Three Hundred Million of Us?

Last night, the so-called "gang of six" -- three Republican and three Democratic senators on the Senate Finance Committee -- met by conference call and, according to Senator Max Baucus, the committee's chair, reaffirmed their commitment "toward a bipartisan health-care reform bill" (read: less coverage and no public insurance option). The Washington Post reports that the senators shared tales from their home states, where some have been besieged by protesters angry about a potential government takeover of the nation's health care system.

It's come down to these six senators. The House has reported a bill as has another Senate committee, but all eyes are fixed on Senate Finance -- and on these three Dems and three Republicans, in particular. But who, exactly, anointed these six to decide the fate of the nation's health care?
