President Obama's tenure in the White House has not been an easy one, but he has been buoyed by a few lucky breaks. It seems like every time things look particularly bad, Dick Cheney re-emerges and does an interview to remind people just how bad things could be. When the electoral outlook has looked particularly bleak, the Republicans have helped the President by nominating unelectable candidates like Sharron Angle who make it easy for the President and his allies to portray the Republican Party as extremists.
