Uh the Framer's built a winner take all system, and thus the two party electoral system, we have now.
They knew that you can't please all of the people all of the time.
Human nature and all that.
Uh, no they didn't. The very system is based on compromise and the branches working with each other. Granted their intent was that we would not be voting for President or Senators, which I have no problem with and would prefer. Human nature took us that path of a two party system, as evidenced by Washington's Farewell Address and the warnings found therein.
