When it serves his purpose to berate King for asking a question about his second marriage, Gingrich gamely takes on the task. The rest of the time, he dispatches his daughters to explain his extramarital activities.
In the end, I believe that Republican primary voters are too pragmatic to nominate such a flawed candidate. So I'll go with Pitney, who explained, "In South Carolina, people were trying to send a message that they didn't like the mainstream media, but if it starts to appear that Gingrich has an actual chance of winning the nomination, then it's a different vote. People's calculations will change."
