Republican Senator Olympia Snowe really stood in the face of her party and recognized how big today's health care vote is by voting in favor of the Baucus bill. She was also heavily courted by Obama to vote for the bill. Why? From what I have been reading, it will hopefully cause conservative dem senators to vote for it as well. Meaning, this will probably be the backbone of the main bill that makes it to Obama's desk.
Some of Olympia's quotes:
"When history calls, history calls."
but: "My vote today, is my vote today. It doesn't forecast what it will be tomorrow."
So will she be in the final floor vote? Probably not.
