Defeatism around something so critically important to the success of a country isn't a plan.
Absolutely, one of the big systemic changes we need to effect is a switch to ranked choice voting. There are several other significant changes to the US's voting system that would also be needed. Things like a complete elimination of voting machines, and honestly a full switch to vote-by-mail would probably help.
Of course, the voting system in this country isn't even the biggest problem, some how. Things need to change before next election, not in a few election cycles.
Obviously it would be really REALLY nice if there was a trustworthy entity who could do that, but it's pretty absurd to suggest that if we simply vote for the other guy suddenly the US government will be that entity.
