It has been apparent for some time that Marco Rubio's political skills are less impressive than most people assumed several years ago. During the government shutdown/debt ceiling debacle he was either invisible or confused, ricocheting between extremism and quiet moderation, but at all times appearing like a man who didn't know what to do. In one corner, the business community. In another corner, Tea Party activists who will vote in a 2016 Republican primary. The result: flailing.
