ObamaCare has always been controversial, routinely blasted by the GOP. But now, Sebelius is taking some friendly fire.

A liberal lawmaker who requested anonymity said, “She’s been terribly defensive, terribly slow to react.”

“There have been many conversations among progressives about this. We want a personality that acts to confront any glitches immediately — more of a nose-to-the-grindstone manager.

“If there is any more defensiveness as we’re implementing, it will be a huge issue in 2014.”

Many Democrats, however, came to Sebelius’s defense. Others blamed the White House.
