It's the same in local government. I know a firebrand Tea party fellow who not only works for the city of San Francisco as a legal administrator, he's a member of the AFSCME (white-collar public sector union) and brags about clocking out on the dot of 5pm. I think the attitude is that other people are getting this great deal, so why shouldn't he?

Mind you, I'm not exactly consistent either. I'm quite liberal but I far prefer working in the private sector or even freelance and have never joined a union. Perhaps our political views are an expression of frustration with the negative aspects of our life choices.
