I'd vote for Wight, he seems like he has a good head on his shoulders, a loving family man who'll probably lead with good intentions. The rest of the candidates all look like they'd scheme ulterior motives... probably destroy the world in the process.
I really want to see them all have to debate one another... honestly I think Maximus has a pretty good chance if his cover isn't already blown...if zombie monsters get a vote, which they should though... I think Balerdroch has this in the bag, considering they're depicted having rule over all of Zombie world...or at least a good chunk of it. My personal vote, however goes to Eldlich I mean he offers eternal perfect healthcare (becoming a golden zombie), a 401k and has cash for Days...might have an ulterior motive but let's be real, which historical leader hasn't had an ulterior motive in the past 1000 years?
