The firestorm over President Obama’s “you can keep your plan” lie now threatens to singe vulnerable Democrats next year, so they’re springing into action to try to force the administration to keep its word. Louisiana’s Mary Landrieu — an ardent Obamacare supporter — is scrambling to undo one of the obvious consequences of a law she’s voted to pass, fund, and retain:

Sen. Mary Landrieu said Wednesday she would propose legislation to ensure all Americans could keep their existing insurance coverage under Obamacare, a fresh sign of the political problems the law’s rollout has created for congressional Democrats. Landrieu, a Democrat who faces a tough reelection in Louisiana in 2014, said she would either offer her own bill or formally sign onto another measure that would ensure that the law would not force anyone off of their existing health policies. “The promise was made, and it should be kept,” Landrieu said in the Capitol Wednesday. “And it was our understanding when we voted for that bill that people when they have insurance could keep with what they had. So I’m going to be working on that fix.”

If that truly was Landrieu’s “understanding” at the time, she’s a moron. I’ll let Steny Hoyer explain why. The more likely explanation is that she’s a committed Democratic partisan who was willing to do the White House’s bidding in order to drag Obamacare across the finish line via lies and sweetheart buy-offs. Her repetition of the president’s “keep your plan” nonsense was either the product of (a) unforgivable ignorance or (b) self-interested cynicism. The latter option sounds about right because it also explains her sudden reversal on this point. She now professes to be shocked — shocked! — that people can’t keep their preferred coverage. Republicans have been aggressively challenging Obama’s ludicrous promise since it was first made. Those warnings fell on willfully deaf ears. Responding to Republican accusations that she’s finally kicking up a fuss to cover her own political ass, Landrieu had the audacity to accuse the GOP of “making things up,” and said she expects to be re-elected next fall.
