MA had this as a referendum question last year. Even the far-Left Massachusetts voters rejected this as a terrible idea.
Unfortunately, we have it Maine and it cost us the Republican House seat in CD-2. He won the election on election night but lost it after the rank choice voting was allocated.
The sad part of this story is that the advocates of rank-choice voting were left wing Democrats (yes I know the same) and far left-wing Marxist/Leninists types.
And of course the Maine Republican Party fought the proposal with tooth and nail (NOT). The party just went along its merry way humming and skipping down the road and playing nice.
