The same amount of privacy the rest of us get to experience. Which, I suppose with the NSA still going strong, is zero privacy.
Don’t get me wrong, I believe all individuals deserve complete privacy as guaranteed in the Constitution. You know, that whole 4th Amendment thing to the United States Constitution. Oh, and the privacy section in the state constitution. I don’t know where people get the crazy notion that because a person is elected, they have to give up their private lives. I don’t see any place in the Constitution where it says only certain individuals are guaranteed the right to privacy. Though maybe most people who vote believe they are electing criminals? You are probably voting for the wrong person if you believe you need to know the last place they filled up for gas.
