As the speculation about who Mitt Romney will pick as his running mate picks up, it seems clear that, despite some hints, it is highly unlikely that he will select a Governor or former Governor as his Vice Presidential choice.
The last time that two Governors ran on a Presidential ticket together was 1948, when NY Governor Thomas E. Dewey ran with California Governor Earl Warren, losing to President Harry Truman.
Also, in 1944, Dewey had run against Franklin D. Roosevelt and lost, with Governor John Bricker of Ohio as his Vice Presidential choice.
Those are the only times in the 20th century that two Governors ran together, with the choice otherwise usually being a Senator running as the Vice Presidential choice of a Governor.
So do not expect New Jersey Governor Chris Christie, Louisiana Governor Bobby Jindal, Virginia Governor Bob McDonnell, Indiana Governor Mitch Daniels, former Florida Governor Jeb Bush, or former Minnesota Governor Tim Pawlenty to be the choice of Mitt Romney!
