I never took Gingrich's candidacy seriously. Why should I? Some of his top staff members quit because they felt that he was not taking his campaign seriously. But he suddenly vaulted to near-front-runner status as the current anti-Romney.
What are you thinking, people?
Newt's main qualification is that he was speaker of the house for a while. He wasn't particularly successful and was forced out by his fellow Republicans. While he was speaker the government shut down twice. The rumor at the time was that Newt shut down government because he wasn't given special seating on Air Force One. This was false but the fact that the Clinton administration managed to tar him with it shows how easily he can be out-maneuvered.
Newt has so much baggage that he needs a porter. Romney switched positions on abortion. Newt switched on nearly everything. He supported a federal mandate on health care while Obama was still a community organizer. He made a joint statement with Nancy Pelosi about the hazards of global warming.
Newt's personal life makes Bill Clinton look like a boy scout. Clinton strayed repeatedly but he never left his wife. If Edwards and Cain have been disqualified from running because of their affairs, how can anyone support Newt? Electing him brings back the possibility of a new presidential affair. A lot of social conservatives will stay home or vote for Obama rather than endorse Newt's infidelities.
Newt has worse baggage. He has earned millions as a lobbyist for recipients of federal bailouts.
Newt describes himself as a historian although he left academia rather than publish original research. That makes him a guy who got a history degree by reading the books published by actual historians.
Newt has a long history of shooting from the hip. This often gets him into trouble. It would be better if he was not in a position of importance.
