History professor Gingrich is probably the smartest person running for the 2012 Republican nomination, and undoubtedly the most fun to listen to. Unfortunately, law professor Barack Obama was the smartest person running for the Democratic nomination in 2008 and the most fun to listen to. He hasn't turned out so well as president.
Professor Woodrow Wilson also didn't turn out particularly well as president. People said Reagan wasn't really bright and he was a good president.
I spent my career being paid to be smart. It troubles me to say intellect may not be a major qualification for president.
I'm concluding Newt shouldn't get the nomination. I believe we need a successful governor as our president: Daniels, Pawlenty or Christie. On the other hand, if had to pick an after-dinner speaker I'd pick Newt, hands down.
