Various anime characters
Light Yagami (Death Note)- would’ve voted for Hillary. Both are criminals who think they’re doing the right thing. Both support murder (in Hillary’s case it’s Abortion)
Ryuk (Death Note)- See above
Goku (Dragon Ball franchise)- Trump. Both are heroes who care about their world and everyone in it.
Vegeta (Dragon Ball Franchise)- Hillary. Very self centered and egotistical. And so is Vegeta.
Frieza (Dragon Ball Franchise)- wants to rule the universe with an Iron fist. So Hillary.
Naruto (Naruto franchise)- votes Gary Johnson
Sasuke (Naruto Franchise)- Gary Johnson
Eren Yaeger (Attack on Titan)- Hmm. Probably Jill Stein... sadly.
I could easily see the whole cast of AoT being socialists. There's hints here and there, especially from Levi.
Haven't watched the 3rd season of AoT but here goes nothing:
Eren: Left-wing single-issue voter, cares about justice and winning. Bernie->Stein
Mikasa: Votes with Eren. Bernie->Stein
Armin: Intellectual, worldly, not afraid to think outside the box. Bernie
Jean: Elitist, self-centered tool whose perspective changes upon joining the Survey Corps. Rubio -> Hillary
Sasha: Rural, working-class, cares about survival but is also a foodie. Tossup between Trump and Hillary
Connie: Practical common-sense type. Tossup between Trump and Hillary
Reiner: Publicly pro-Hillary/Bernie, but privately supports Trump
Bertholdt: Privately a Trump voter but sympathizes with Bernie and Stein voters
Annie: Individualistic, aloof, joined the Military Police. Canon Trump voter but I can see her supporting Johnson
Ymir: Apolitical
Krista: Seems like a noblesse oblige SJW type. Hillary->Bernie/Hillary
Levi: Left-wing, populist, anti-corruption. Staunch Bernie supporter
Erwin: Survey Corps leader, leans GOP. Reluctant Hillary or Bernie supporter
Hange: Mad scientist type. Liberal but can't see her supporting any of the 2016 candidates
Pixis: Libertarian, pro-Johnson.
