Health Care Reform: Cut To The Chase

This guy has it down in an easy-to-digest article:

But if Snowe signs on, according to nearly every person I consulted, it’s quite possible the legislation she supports would become the Senate’s bill with very little change--and that, in conference, the Senate bill would prevail. She’d hold the leverage, as long as the administration and Democratic leadership prefer to pass pass legislation with 60 votes. And that certainly seems to be the inclination of Obama and his advisors. (It's harder to tell about Congress, particularly the House, but they're unlikely to challenge the White House openly on this.)
Unless, of course, it never gets that far. Snowe may not sign on; even if she does, one source close to the process notes, she "may not bring a sufficient number of conservative Democrats" to reach 60. If that happens--if consensus proves elusive, for whatever reason--then Obama and his allies would focus on trying to pass a bill through reconciliation. And they would move quickly.
