You just know that Groundskeeper Willie is a Trump guy. Bar owner Moe probably is too. Mr. Burns and Chief Wiggum are GOPe. So they probably supported Jeb Bush. Marges sisters seem like Hillary people. The rest of them probably went for Bernie Sanders.
(My wife thinks Im wasting my time posting in-depth analyses like this one. She is so provincial.)
