Yeah, but then, if, say 20% of voters in swing states voted third party, it would let the greater evil in, this being the very immoral choice.
Surely a more relevant measure is what can I do that will do the most good. Voting for someone who is better than the other realistic option, this keeping extremists out of power feels like a more moral option than making a pointless vote.
Yeah, but ranked choice isn't in operation, so you've got to make the better choice for right now.
Also, in that case Trump would be the better option. I would hope that in a scenario where the republicans had nominated Hitler that the democrats could do better than Trump but if they couldn't, then yes, voting for Trump in that scenario would be r the right thing to do as voting for, say, Bernie Sanders I. that scenario would let, you know, Hitler become the President.
