The Hill reports:

Grassley, the ranking member of the Finance Committee, said that Chairman Max Baucus's (D-Mont.) healthcare bill would pass 13 to 10, suggesting that the closely-watched Sen. Olympia Snowe (R-Maine) would vote against the proposal. "It'll pass probably on a party line vote of 13 to 10," Grassley said in a news conference with Iowa reporters.

Update: The AP reports Snowe will vote yes on the committee bill, but hasn't committed to voting for the final legislation.
