We need to abolish the "2-party system." This is a false dichotomy that was inflicted upon us by the power elites. There's nothing in the Constitution that created it.
IMO, the more parties, the better. In this way, we hope that no single party has complete control. Think about the parliamentary systems and how they must power-share to get anything done.
I'm all for founding a Constitutionalist Party that's primary platform is to reverse all unconstitutional laws and court opinions so that we're back to what was originally intended. I'm not a keen fan of judicial precedent as it allows bad decisions to linger ad-infinitum.
