I don't mind talking about my political leanings, but I don't wear it on my sleeve or on my car. In my profession, I have to work with organizations and government agencies from across the political spectrum. I seek out commonalities. We are all working towards the same goal, and sometimes a bumper sticker will get in the way if someone comes to the table with a preconceived notion of who they are dealing with.

But y'all aren't my profession, so I'm happy to say that I'm very much on the liberal (in the U.S. political system sense) side of things, mostly.
