In a recent Rolling Stone interview Barack Obama was quoted as calling Mitt Romney a "bullshitter"

“We arrived at the Oval Office for our 45-minute interview … on the morning of October 11th. … As we left the Oval Office, executive editor Eric Bates told Obama that he had asked his six-year-old if there was anything she wanted him to say to the president. … [S]he said, ‘Tell him: You can do it.’ Obama grinned. … ‘You know, kids have good instincts,’ Obama offered. ‘They look at the other guy and say, “Well, that’s a bullsh–ter, I can tell.”’”

Barack Obama seems to have taken a turn from his 2008 campaign, which I would call "No record to run on", and begun one of the worst smear campaigns in history. Recall though Obama said it himself:

If you don't have a record to run on, then you paint your opponent as someone people should run from. Obama acceptance speech

Well Barack one thing is for sure, you don't have a record to run on...
