Since voting in the USA is controlled at the state level, it would require a different effort on each state to replace First-past-the-post voting and other crucial reforms. Alaska has Ranked Choice Voting actually, despite conservatives putting ballot initiatives to go back to FPTP voting every election cycle.

The good news is that means electoral reform can happen easier at the state level then trying to push shit through at the federal level.

The bad news is liberals in this country get rock hard when they yell and scream at those disenfranchised by the two party system. They adore their chains.
