The Senate Finance Committee is awaiting a cost estimate, or "score," from the Congressional Budget Office, and Chairman Max Baucus (D-Mont.) said today he's unsure when it will come.

"I'm hopeful it's tomorrow, but I can't guarantee it," Baucus said after emerging from the Senate Democrats' weekly luncheon.

Movement on his health care bill has stalled so senators on the committee, especially Sen. Olympia Snowe (R-Maine), can cast their vote knowing how much the bill will cost. As for when a vote will take place, Baucus said it all depends what the CBO score looks like.

"If it's a clean bill of health," the vote will take place sooner, said Baucus.

Asked if he had spoken with CBO during the process and what he expected in the score, Baucus smiled and said, "I'm not discouraged."
