Yes, essentially we can just keep the main leaders of each party and assign them everyone's votes from their respective parties (35% in your example) that "won" and get rid of everyone else and end up with the exact same outcome, except orders of magnitude cheaper and more expedient. If you're a member of x party and x party won, why are you actually needed if you're not the leader? Your salary, benefits, retirement and as well as every single person on your staff are all a waste at that point, because you're going to vote for x's position, which is decided by the leadership.
