According to Politico and the Associated Press there have been mass resignations at the top level of Newt Gingrich’s presidential campaign. Politico’s Jonathan Martin says campaign manger Rob Johnson, strategists Sam Dawson and Dave Carney, spokesman Rick Tyler and consultants Katon Dawson (former Republican state chairman in South Carolina) and Craig Schoenfeld of Iowa have all resigned en masse “to protest what two officials called their ‘different vision’ of the campaign.” This is dreadful news for Gingrich’s candidacy, of a sort that may have been foreseen when Pete Wehner of Commentary and the Ethics and Public Policy Center predicted that Gingrich would get out of the race before the end of the summer and David Shribman of the Pittsburgh Post-Gazette asked why so few of Gingrich’s associates from the 1990s were supporting him this time. One justification for the long hard slog of the presidential nominating campaign is that it tests a candidate’s ability to manage. In this case there seems to have been some major problem. It’s hard to see how Gingrich’s campaign survives this mass defection.
