By "end the Duopoly" you just mean "help billionaires get gigantic GOP tax cuts'. We've had dozens of 3rd parties and they have all been failures. The system has structural forces in place to prevent them from being successful. Nobody alive today created this system. We are all stuck with it same as you. But we recognize the reality that millions will die or become impoverished every time someone like Traitorapist Trump gets elected from his party of corrupt decadents. And we recognize the reality that when the GOP wins it is us who loses, not politicians.
