20. Sarah Palin
Once Sarah Palin was released from the Alaskan wilderness to run for office with John McCain, it became extremely hard to shut her up. That happened years ago. Sadly for the public, her barrage of idiocy continues.
The most aggravating and uncalled for Palin comments of 2012? One has to be her criticism of the Obamas' Christmas card because of its emphasis on Bo, the family's dog, rather than on "family, faith, and freedom." What? Another great one: when she called out fellow Republicans for being "establishment cannibals." We have no idea what that means, but it sounds gross.
