The House passed the healthcare bill late last night, 220-215. Only one Republican, Joseph Cao (LA-02), voted in favor. Here are the Dems who voted no:
Stephanie Herseth Sandlin
There was also a vote on an anti-abortion amendment, which passed 240-194. Sixty-four Democrats joined all Republicans in voting for this amendment. (John Shadegg voted "present.")
P.S. I don't like having to do this, but I'm going to remind everyone in advance to keep it civil on this thread. This is the place to discuss the electoral reasons why members of Congress voted the way they did, and the electoral impacts of those votes. Before you hit "post," think about whether your comment falls under this description. If not, it's probably off-topic.
UPDATE: In comments, DCal has a good summary of which Dems in R+3 or redder districts voted yes, and which Dems in R+2 or bluer districts voted no. Also, the NYT has a great interactive chart detailing the Dems who voted no.
