If we want better choice next time, we better start working on them now. Imagine how difficult it will be to entice good persons to enter the presidential arena after seeing the melee there. Imagine placing yourselves and your loved ones in the eye of a public hell bent on excoriating the opposition.
The most important task that I can see is convincing everyone that this presidential election is our fault. If you must point a finger of blame, point it at We the People. Yes, it might be easy to blame the establishment, but remember, they would not exist except by our indifference, our silence which provides assent to their rule over us.
