No, they'll just be confused as fuck, and the ruling class (primarily leftists) will swoop in to feast on the carcass.
You really have no idea what you are talking about. RCV would be a significant blow to the stifling dominance of the two party shitshow. Voters would be able to vote for the candidates they truly believed in, as their first choice, without the fear that it might "help" some other candidate who terrifies them. That lame assed excuse goes away entirely with ranked choice voting.
Many voters like to tell themselves that they're not really voting
for candidate x, they're voting
against candidate y. But under our current system, you can't actually do that. All you can do is guess who has the best chance of beating the jerk you hate and vote
for them.
With ranked choice voting you actually can vote against a despised candidate. By ranking a candidate dead last, you are, actually and literally, voting for every other candidate over them. It doesn't matter who is considered most likely to beat the jerk candidate, whoever it is will get your vote.
Moreover, the icing on the cake, we'd finally get a real read on what people value. Are libertarians really less that 1% of the voting public? Maybe, but I suspect it's a lot higher. And with RCV we'd finally find out.
