1. Finish up the House-Senate negotiations quickly and hold a vote before Scott Brown is seated. Republicans will scream, but how could they scream any louder? It's a process argument of murky merits that will be long forgotten by November.
2. Get the House to pass the Senate bill, and maybe use a reconciliation bill (which only needs a Senate majority to pass) to implement as many House-Senate compromises as possible.
3. Go back to Olympia Snowe. I have not seen any persuasive reporting, or even conjecture, about what Snowe is actually thinking. Her substantive demands have been met. By the end of the process, her only demand was to delay the bill by some unspecified time period, which is such a vacuous demand that it's hard to believe it represents her actual beliefs. Did she turn against the bill completely? Did she decide that she couldn't take the heat for voting yes? Or did she figure that, with sixty Democrats, her voted wouldn't really be needed so there was no reason for her to take the heat? If options 1 and 2 fail, we may find out about Snowe.
