So, Romney's past is fair ground for attacks now, all the way back to when he was 6-10 years-old

In January, Obama campaign honcho David Axelrod tweeted a photo of Obama's dog, Bo, riding in the president's armored limousine, with the caption "How loving owners transport their dogs." On Tuesday evening, Romney campaign spokesman Eric Fehrnstrom retweeted Axelrod with the comment, "In hindsight, a chilling photo."

Obama campaign spokesman Ben LaBolt responded with a tweet questioning Fehrnstrom's decision to embrace the story from Obama's childhood: "What's the next attack @EricFerhn and the RNC will surface on a 6-10 year old?"
