There is no fixing the electoral system. You’re not going to fix a company from the inside. They will ban ranked choice voting if it ever starts gaining traction.
Two major examples of this are Bernie Sanders being ousted by the establishment when he was about to win in 2016 and UK’s Jeremy Corbyn who got straight coup’d by Zionists because he was about to win.
Democrats will use every dirty trick in the book they never use against Republicans if someone comes up who will challenge the establishment. The moment the elite is endangered they will break every single rule in the book to overthrow their challenger.
You cannot change the system from the inside if the people are the top have already proven they will never allow that.
