According to FNC's Greta Van Susteren, Cameron told her he “messed up on this one,” referring to the laundry list of anonymous GOP attacks (smears?) that were broadcast about Palin after the election.

Like the claim that Palin didn't know Africa was a continent, she was a shop-aholic," clueless about NAFTA, and that she once answered a campaign hotel room door wearing a bathrobe.

The claims set off a firestorm within right-wing media circles. And now Cameron regrets it all.
