There is something interesting about the users saying Fuzzy or Spectator, though -- it's often remarked upon in religious contexts that the people most enthusiastic about some dogma are converts, those who actively chose it recently. Similarly, it wouldn't surprise me if the people most enthusiastic right now about being Republicans or Democrats are those who actually supported the other party not too long ago.
(I think Spectator still identifies as a Republican -- and still supports the GAGOP at the state level, correct-me-if-I'm-wrong -- but he does seem to be one of our most enthusiastic supporters of the national Democratic party.)
Another blue avatar who I wonder why they still have a blue avatar is AHDuke99 - since from I have seen from his posts, there is barely anything in common with the GOP and I wonder why he still identifies with a party he seems to hate virtually everything about.
