Which will never happen because the Republicans are dead set on never changing any system in any way that’s not directly in their benefit and no one else’s. Until that moment arrives, which is never, the only option is to pick your particular flavour of straight-up fascism (Republicans these days) or anything else (Democrats) in the party primaries.
Don’t fool yourself. The DNC also doesn’t want ranked choice voting. Neither party wants any competition. The entire system is built to make it virtually impossible for a third party candidate to win. Unless they actually hit 270+, even if they were a clear majority winner, they wouldn’t be elected.
One of the few advantages of our splintered system of states is that voting is done on a state level. We can implement ranked-choice voting in states where Republicans are weak, and in doing so, allow states that aren’t filled with fascists to choose between multiple non-fascist ideologies, instead of just fascists and ‘whoever is left’.
The dnc also doesn’t want ranked choice voting. Even worse, if you managed to pass rcv in a heavily left state, it would only end up muddling up the waters on votes in house and senate, where the amount of Republicans would stay the same, but democrats and third parties would be sharing what used to be just democrats.
