I'm in favor of Rank Choice Voting for this reason. Our system makes 3rd party votes hard or impossible, so instead of voting for who you like, you have to vote for who you dislike the least.

Let people vote for who they like the most without fear of their vote bolstering a candidate they really don't like. We should start exposing kids to RCV in schools. Now. It needs to not be "weird" or "hard" or propagandized as "not fair." Not fair is not being able to vote for your favorite person.

US biggest existential crisis is the fact that the opposition is always a monopoly.

So either you have a massive win, or a party will block the other forever out of spite, nothing can be accomplished and no mistake can be fixed. With more opposition groups the situation would change for good ("You don't want to make a deal with me, I will ask the third and fourth parties. The first team doing a reasonable move gets the prize").
