so the best that can be done is vote for the least fucked up option and work to improve things.
Democrats were good at the first part, but not the second. I remember lots of Dems saying “Vote for Biden, and then we’ll hold his feet to the fire!” Well, there was no “holding his feet to the fire”, because that’s seen as enabling Trump.
The perfect candidate/option does not exist and never will
Yes, but there are candidates who are better, such as Jill Stein and Cornel West. You can’t vote for a perfect candidate, but you can vote for the best candidate.
