Sen. Joe Lieberman (I-CT), whose vote would most likely be necessary to break a Republican filibuster on health care reform, said Thursday that he's "inclined to let the motion to proceed."

But, he added, "I haven't decided yet."

The New Haven Register reported Lieberman's remarks today. Lieberman said earlier this week that he doesn't support the Senate Finance Committee's version of the bill.

Lieberman votes in the Democratic caucus and counts as one of the 60 Democrats.

As Rep. Barney Frank (D-MA) said today, something like the public option won't need 60 votes. Democrats only need 60 votes to break the filibuster -- but the final vote on the bill only needs 51 votes.

"It is conceivable that some Democrats, for example, would vote to break the filibuster who would then vote against the bill," Frank told Joy Behar on Headline News.
