Questions About Patrick Nielsen Hayden

Which liberals might vote against healthcare?

Which liberal (or at least pro-healthcare-reform) Democratic senators are leaning towards opposing the current bill? I've been convinced that, as Patrick Nielsen Hayden put it, we should pass the bill anyway. I'd like to know who to write/call in the Senate to make sure that happens. I know that Firedoglake, Kos and some other "netroots" types are agin it, but are any senators actually following their advice? Roland Burris, maybe? Google hasn't helped me much here: the keywords I choose send to a huge mess of articles. Please don't pitch in with reasons why we need to oppose the bill. You may be right, but that's not what the question is about. Soothing advice that I don't need to make any calls and that the bill is definitely going to pass now are, however, quite welcome.
