The stress of running for president appears to be getting to Newt Gingrich. He's started saying some impolite things; he seems to feel like his best qualities aren't being appreciated by the media, who are fawning over the other candidates. Those qualities include: he's smarter than the rest of the field, NBC's Anthony Terrell and Domenico Montanaro report. At an Iowa breakfast Friday, Gingrich said, "[I]f you watch them and watch me, the difference in the depth of knowledge and the difference in the ability to debate Obama, the difference in actually having done it at the national level, I can't only think if you're worried about the future of the country and you're worried about how we get the country fix, I’m a pretty good mechanic who knows how to fix the car and the other folks are good at selling it." Then he generously added, "They’re nice people, but they don’t have the knowledge to do something like this on this scale. This is enormously complicated."

That campaign stress might be getting to him was evident Thursday, when the Los Angeles TimesSeema Mehta asked about his fundraising in the third quarter. Gingrich snapped, "See, I knew you couldn't resist. I'm not going to answer you... You should really go home and think about why you would even ask that today." Gingrich's campaign ended the second quarter $1 million in debt, but at that moment, he wanted to talk about his updated Contract with America.
