Mrs. Robinson- Clinton
Benjamin Braddock- Sanders in primary, torn between Clinton/Stein/not voting in general
Mr. Robinson- Trump
Elaine- Sanders in primary, torn between Clinton/Stein/not voting in general, maybe slightly more pro-Clinton than Benjamin
Mr. Braddock- Trump
Mrs. Braddock- Seemed disengaged, so possibly a non-voter, but if she did likely would have voted for whoever her husband was
Here's an idea. Obviously all the West Wing main characters are partisan Democrats, but also ideologically pure saints, so which of the two would they support?
Everyone on The West Wing would support Clinton. The lower level people who might not have in theory (Donna, Charlie) were way too ideologically moderate to vote Sanders.
Gloria: Clinton (A Woman, feminist, liberal but not that much, seems like it.)
Micheal: Sanders (Male, Egotistical, hippie, has anti-woman prejudices, will make anti-Hillary slurs, vote for green and never for Hillary.)
Michael would have hated Trump so much that he would vote for Clinton in the end just to stop him. It's not like Carter was a huge leftist and he voted for him.
