I am not sure why everyone thinks it would be a punishment to fire Sebelius at this point. Three days after she is fired, she will have a handful of million dollar a year job offers from health care companies and lobbyists who want to tap her influence into this administration. The Administration and Congress is actively picking winners and losers in 1/7 of the economy, so there are billions at stake. Sebelius can name her price.
Instead I would love to see her stay in office three long years and answer every press question and Congressional inquiry about Obamacare, over and over and over.
