Our President being the leader of the free world has amassed great political and military power. The last two presidents have extended the police powers of the Executive beyond recognition. He is no longer a constitutional figure and our republic is a historical notion. The Congress has given up its constitutional power in favor of the “national security interest” which has little to do with security and even less that is truly national. It ceded the war powers to the President long ago and recently the “power of the purse” to the Federal Reserve and the Treasury. The Commission on Presidential Debates is a political operation of the Presidency with the opposition political party in contrast to an independent commission. The many departments of the general government are extensions of presidential power. Our president oversees the global political economy without legal authority and only appears in domestic political arenas during the campaigns.
Political thought is elastic not dualistic. In our constitutional system we have three branches not two and the political parties are not found in our organic law. See http://www.p2012.org/parties/
I wonder if the parties collapsed due to political failure–would civil order fail too? Or would democracy evolved into a more obvious totalitarianism? The elastic nature of democracy would favor more political diversity if that is truly the nature of our current system.
