So Yglesias is now shilling his "You might lose your House seat but make history" line over at the Daily Beast. But how will those Democrats who waited until the last moment to collect the final payoff or who broke under pressure from their party (or both), before they voted yes on Obamacare be remembered even by sympathetic historians? How do we remember Marjorie Margolies-Mezvinsky? She was the House Democrat who buckled to the House Democratic leadership at the last moment and voted for Clinton's tax increase in return for a promise that Clinton would go to her district for a pr show. She lost her House seat, but I don't think that historians who stoop to notice her will see real heroism.
My impression is that she is remembered as a case study of how congressional leadership can intimidate and bribe weak-willed caucus members into politically suicidal acts. So perhaps the wavering House Democrats face a more complicated choice than they might assume. If they switch at the last moment, putting aside their principles (if they have any) and the will of their constituencies, they might well get a place in history. But it might not be the place in history that Yglesias is offering. They might instead, get the place in history that they deserve.
