And then there was one. Mary Landrieu confirmed today she'd vote in favor of allowing the Senate health care bill to move forward. "Much more work needs to be done," said the Louisiana Democrat, but she's seen enough modifications for now. She warned this doesn't mean she'll vote in favor of whatever final legislation emerges down the road. Heading into tonight's 8pm vote, that leaves one Democratic holdout in Harry Reid's quest for 60 votes, Nebraska's Blanche Lincoln. All 40 Republicans are opposed.
