Putting some thoughts here, while they are on my mind:
Political parties and news organizations love to pretend that an election is an ideological mandate. When the candidate you vote for wins, it’s fun to feel that way.
I think an election is simpler, it’s a snapshot in time, and it’s very much about who is on the ballot. Sometimes a vote is yes to a candidate, to a party or to a platform, but sometimes a vote is against a specific person. I suspect that the 2016 and 2020 elections reflect this in America more than Americans traditionally would admit.
