A new poll finds that most Americans believe that President Obama and his health care team knew well in advance that insurance costs would surge despite his promises they wouldn’t, and as a result 40 percent want Health and Human Services Secretary Kathleen Sebelius to retire or be fired.

Rasmussen Reports found that 71 percent of voters believe “it's at least somewhat likely that President Obama or senior officials in his administration were aware long before the law began being implemented that health insurance costs would go up for some Americans.”

Worse for the president: Only 18 percent want Obamacare to move on unchanged, but 43 percent want it repealed and the process started over and another 35 percent want Congress to fix it in a piecemeal fashion.

Although bad news for the president and his namesake law, the public is divided over Sebelius, who this week took full responsibility for the poor rollout of the Obamacare website. According to Rasmussen, 40 percent believe she should be fired or resign, but 41 percent disagree.
