WASHINGTON (AP) - Democrats have hit the magic number of 60 to move ahead on historic health care legislation.

Arkansas Sen. Blanche Lincoln said on the Senate floor that she will vote with her party, hours before the 8 p.m. EST roll call.

She said it was important that the Senate begin debate on a critical issue.

The centrist Democrat was the lone holdout.  Facing unanimous Republican opposition, Senate Majority Leader Harry Reid needed the 58 Democrats and two independents to vote to move forward on the sweeping bill to remake the nation's health care system.

Shortly before 1 p.m. EST, another centrist fence-sitter, Democratic Sen. Mary Landrieu of Louisiana, said she would vote yes.
