And look what happened to Perotistas. Their "Reform" party has split into a half dozen irrelevant constantly squabbling forever minority party's.
It seems to me your fundamental principal is you just dislike the two party system. I guess I do not get that. Parliamentary systems require EVEN more compromising of principals to form a Government. If you object to RINOS, God help you in a parliamentary system that might require you to accept Democrats or Greenies or other moonbats in your cabinet to achieve the parliamentary majority to govern!
