I'm afraid that I have to agree with Matt Yglesias about the latest Newt flap: in the world Newt is engaged in, it makes perfect sense to say that there's a grave danger of the United States becoming a "secular atheist country...dominated by radical Islamists." I mean, it's nuts, but it's not really internally contradictory in the sense that people are laughing at him about.
So since I can't pick on that...well, other than to note that it's nuts, I'll turn back to yesterday's Newt flap, which was Greg Sargent catching him rewriting the history of his position on Bill Clinton and impeachment. Newt, now, understandably, would like everyone to believe that it was only a legal matter and had nothing to do with condemning Clinton's morality or private personal behavior, but of course that wasn't actually the case back then.
This reminds me of my absolute favorite Newt flip-flop, which is also from 1998. In a TV special about Newt and the 1998 election (I think it was Frontline, but I don't have my copy with me right now) shot during the campaign, Newt spends quite a bit of time complaining that the press will discuss nothing but Lewinsky. Unmentioned, however, is that earlier that year the soon-to-resign-in-disgrace Speaker had pledged to raise the scandal in every single public appearance.
Of course, because on principle, and probably by temperament, Newt insists on taking everything to the extreme at all times -- he's going to talk about Lewinsky in every appearance, and Obama is the most corrupt president, and this is the most critical election ever (note: not actual quotes, although I've heard him say things like each of these but don't really feel like looking them up right now...and granted that everyone always says that every election is the most critical one) -- Newt is easy to catch contradicting himself in spectacular ways. The right thing to remember about him isn't that he flip-flops (that's common enough among politicians), but that he customarily dresses up trite comments and claims in fancy-yet-extreme language. In other words, he's just a snake oil salesman.
