Believe it or not! It is not a requirement in the Constitution. In theory you can be an illeterate, mentally retarded and just about anything else and you can still be a Senator. The Founding Fathers made the assumption that the American People would set the criteria with such things as newspapers, gatherings and political debate. You can sit on the Supreme Court w/o a law degree. There is no stipulation in the Constitution that a person has to have a law degree from some school like Harvard. In my opinion if we had a few people w/o law degrees, we might get a court that believes more in the Constitution then their own brand of what the Law should be according to their own legal philosophy.
