I used to mainly vote third party as a protest vote for both sides to do better. Didn't matter the party, really.
I voted for Obama out of genuinely wanting him in office. I thought he was decent overall but he did disappoint me.
I voted for Biden purely to keep Trump out of office. Even so, I think Biden has largely been a better President than Obama was, though the Gaza/Israel thing is really testing that. I would love to have a more progressive choice, but any time I am disappointed in Biden, I just remind myself the alternative and I would crawl across a mile of broken glass to vote for him.
So I would anecdotally say this election is outside the norm.
