The head of the National Rifle Association mocked President Obama's Rose Garden "tantrum" after losing the gun control fight in the Senate, charging Thursday that Obama suffered the worst defeat of his presidency because "he bit off more than he could chew."

David Keene told Secrets that the president and his team misplayed their hand because they don't have a sense of the public's attitude toward gun control. "They just can't gauge the public reaction to what they do because they don't have any sense that the public has feelings different than they do," said Keene.
