Brian Schweitzer is an agricultural scientist, a gun owner, and a third-generation Montana farmer. He is also a popular Democratic governor of a usually conservative “red” state. Schweitzer likes to joke that he has a rule for himself: If he stays longer than 24 hours in Washington, D.C., he takes a bath in tomato juice when he gets home -- the classic home remedy for the stench of skunk spray. This is pure Schweitzer. The man is not of the elite, and he is not going to be pulled away from his roots. But Schweitzer has a powerful, homegrown, progressive vision of America.
