Woah there, hold your argumentum ad populum! No ethics model is unflawed and just because deontological ethics work often doesn't mean they don't have problems. Instead of looking at the actions you can take, let's look at the results that could be reached:
- Biden wins presidency
- Trump wins presidency
- 3rd party wins presidency
No 3rd party has ever achieved presidency. Votes for a 3rd party have instead commonly resulted in votes being drawn from one party benefiting the other. So realistically we could generalise to:
- Voting 3rd party: Aiding Trumps victory
- Voting Trump: Aiding Trumps victory
- Voting Biden: Aiding Trumps loss
I hate dichotomies as much as you, these shouldn't be the options, I would seriously love to be proven wrong. Am I missing something?
