I'm actually pretty sure he never will die. He had that demeanor about him. He prolly is planning to out live everyone else in the world and then declare himself Master of the World.
Until then, it's good fun watching him steal perfectly good(although useless) votes from the more valid candidates.
"But don't go!" "I'll be back. . .with more votes!" Same. Here. I bet he just kills politicians that nobody cares about and shape-shifts into them to steal votes from viable candidates to power SkyNet! Conspiracy theorism ftw.
