I voted center, but the political compass puts me more left.  I'm also right there with Mahatma.  It seems a bit strange, I was raised religious/conservative.  I have noticed a leftward trend in my beliefs  over the last 15 years, since becoming an adult.  I don't think I became anti religious/conservative until 4 or 5 years ago, but it is definitely the way I feel now.  
I voted for Kerry only because he wasn't Bush.  I would have liked to have voted for Nader.  I think his ideas are great, he just seems to be too much of a flake.  Interestingly, if you click on the 2004 election on the political compass site, I am in the exact same spot as Nader.
Political compass aside, I still say center.  Both sides are nuts, and dangerous if left unchecked,  in my opinion.
