Via MeFi, Dave's Long Box has a list speculating about the political affiliations of various superheroes, though he loses points for incorrectly casting Superman as a moderate Republican. He's a vegetarian, he's a member of the hated liberal media, he's personally benefitted from a lax immigration policy, he hates nukes, he's pro-science, he's suspicious of big business and corporate fatcats, and I think most of us will agree that both "truth" and "justice" flow left these days.

The best entry is Batman's.

Batman is a true independent, a man of solid principles and baffling contradictions. This may be because he is mentally ill. Batman has an almost paranoid distrust of government institutions, yet believes in the rule of law. He’s an urban vigilante, yet he’s a proponent of gun control. Batman is anti-death penalty to a fault – how many times has he had to capture the mass-murdering Joker and return him to Arkham Asylum instead of the electric chair? Contradictions be damned. Batman follows his own moral compass, and Batman is always right. When Batman votes, he weighs all the options and chooses the best person for the job, regardless of party affiliation or whether they are actually running for office. In other words, he writes-in BATMAN on every ballot.
