Imagine a voter that generally wants to vote for their party. In an election cycle, this voter likes one of the party candidates and supports them actively throughout the primary and caucus season, but their candidate falls short and another candidate becomes the nominee.
The voter wants to vote for their party candidate, because the other party is, of course, y'know... the other party. However, the voter finds their official party candidate to be repulsive, dangerous, icky, and generally bad for the future of the country.
How should the voter vote?
Should they hold their nose and go along with the official party candidate, despite personal objections?
Should they not vote?
Should they write-in a candidate they do want to see elected, even though the party nominated someone else?
Should they switch parties?
Does it matter if they are Republican or Democrat?
Does it matter what year the election is being held?
