Obama's continued audaciousness on health reform could backfire

Ruth Marcus writes in The Washington Post:

The White House does not enter Thursday's summit expecting Republicans to make a deal.

The real target of presidential bidding is his own party -- specifically House Democrats.

My worry is that going for broke and failing will leave no time or appetite for a fallback, scaled-down plan. And the moment to do something on health care -- not everything, but something significant -- will have evaporated, once again.
