Which Scifi Villain Would You Elect President?S

We're sick of watching our would-be commanders in chief descend into mean-spirited wrangling, so early into this presidential election year. If only they could take their cue from our greatest presidents. Like Lex Luthor in the Superman comics. Or Sylar on Heroes, who got to be POTUS in an alternate future. Now those were some presidents we could all salute. Which science fiction villain would win your vote for president of these great United States?
