For 16 years, Newt Gingrich has performed a solo performance art piece where he dances right up to the line of running for president, only to pull back at the last possible moment. For reasons that surpass my ability to understand them, this has only increased his overall mystique with the political press, which enables him to repeat this performance every four years. But on Tuesday, it looked as if Gingrich was going to finally jump into the race and be the first man in the field who could be considered a serious contender.
