Thw ay I see it is this in AK recently 60% of the votes were for Republicans, 40% was for a Democrat that won.
that is how it really works.
Democrats are for the most part are mindless automatons all marching to the same agenda. Republicans are like herding kittens, no two really agree on much.
Given that reality, Democrats are going to slaughter opposition at the polls with graded voting. and it will be rule by a minatory.
Many Republicans are assistant Democrats.
RCV makes that assistance easier and more effective.
