Bill Clinton is picking up on the question: Who Is Mitt Romney? And what does he stand for? We just don't know. He even mentions "Severely Conservative Mitt Romney."
As I wrote a few days ago, the president needs to walk into the next debate and say, "I don't know who I'm debating tonight. Which Mitt Romney has turned up? We don't know. Nobody knows where he stands or what he believes because it changes by the day."
Again, the ten words: “Unlike my opponent tonight, you know what I stand for.”
