Kathleen Sebelius is in the hot seat amid rising angst over the administration’s implementation of ObamaCare.

The Health and Human Services (HHS) secretary is implementing the biggest change to the nation’s healthcare system in decades, and the stakes couldn’t be higher.

ObamaCare will be a top issue for voters, if not the top issue, in the 2014 election. President Obama is aiming to help Democrats retain the Senate and win back the House for his last two years in office. If ObamaCare stumbles badly next year, Republicans could control both chambers of Congress in 2015.

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