Just a thought, for what it might be worth.
1-I think Stupak was offered something post November, to roll over.
2-There have been a lot of Dems announcing retirement the last couple of months. Dems who were up for re-election. Figuring that maybe they would lose, after voting for DeathCare, they'd "retire", allowing another Dem to fill their void. Now some people will vote against Dems no matter what, because of DeathCare, but I'm sure there are plenty of life long dems, who are upset about DeathCare, who will vote for a Dem, if the Dem who voted for it retired.
In other words, they've fallen on their swords, thus removing the object of wrath and scorn, allowing life long Dem voters to vote Dem, because there is no longer anyone to hold a grudge against.
Since Stupak is retiring, why NOT VOTE for the guy taking his spot on the ticket?
Are you suggesting this is another Rahmbo strategy?
Triaging the wounded to help Nancy Pelosi in November?
