Election Oddities

I will be turning in the drastically shortened (?) version of my dissertation next Monday, in time for my advisor to either (we speculated) soak it in blood or in champagne. We would prefer the latter. I really don't want to learn that she has committed hari-kiri or a related act over the election returns.
Meanwhile, my new Voter ID card has arrived; I was persuaded to register in Pennsylvania on the grounds that it is a swing state. So far so good, but why does it say I am a Republican? This bit of misidentification could cause someone to attack me at my local polling place. I did not, on my registration, claim to be any such thing, although I did consider saying I was Independent.
