I agree Dems are pushing it more right now
What I would hope is that ranked choice would give rise to more parties/policies/options - people running on actual platforms, not just a two party system. Then we could actually start to push the country more to the left, because as it is, the US government is generally centre right and getting dangerously close to far right.
What I worry about though is that the second the Democratic party in it's current state sees that they are pushing far more left than they want, they'll try to put the brakes on it again because they don't want to lose their power.
Both sides are not the same, and I'm not trying to say they are. But pretending the Democrats are a left wing or liberal party is just not true - they have been going more to the right than the left for decades.
Either way though, if we can get ranked choice all across the US, I think that would be a phenomenal start to actually being a democracy
