Veterinarian and Politician

Today, Daniel told me about something rather unusual, a veterinarian who is also a prominent politician. His name is John Ensign, and he is a US Senator from the State of Nevada, representing the Republican Party. He is up for re-election this fall, and will compete against the Democrat Jack Carter. I think it is rather nice that a veterinarian decides to go into politics, not that I know much about his politics and ideas, but he cannot be bad for animal protection and public policy on veterinary medicine.
