If Hillary Clinton and 2 of Jason Kander (lost by 79,000 votes); Katie McGinty (lost by 87,000 votes); and Russ Feingold (lost by 100,000 votes) had won in 2016, Democrats would currently have a majority on the Supreme Court.
I'm constantly weirded out by "me voting in two elections didn't make everything perfect, so voting doesn't work"
"Voting doesn't work" is literally a right-wing talking point. If it didn't work, they wouldn't be spending billions to make it harder to vote.
