On our last national poll folks who supported Barack Obama for President in 2008 but are now undecided on how to vote for Congress this year said they supported the health care bill by a 59-17 margin.
That doesn't sound like a group of undecideds that the Democrats could lose to the Republicans, but it sure sounds like a group of undecideds that could decide to sit at home this year if they feel like their votes the last time around didn't accomplish anything.
As we've said repeatedly, the political damage to Democrats on health care has been done whether the thing actually passes or not. Republicans are going to be fired up right through the fall and the small number of Obama supporters who have gone over to the Republicans will come back when the economy gets fixed, not because health care fails. At this point what Democrats need to do is make the base feel like coming out in 2006 and 2008 made the country better, and that coming out again in 2010 is vital to continuing the progress.
