Americans are frequently idiots (explain "Friends" or "Survivor").
Until bjc, American Presidents -- ALL THE WAY BACK TO WASHINGTON -- would end their terms and go quietly into private life, write their memoirs, work towards some cause they love and stay out of politics.
But bj was too good for that -- he became political the day after he left office. And he emboldened the worst President in the modern era, jimmah, to think he could re-enter politics and then did so BEYOND WATER'S EDGE!!!
I am sure GWB will once again lend dignity to the office in his retirement -- but if either hussein or mrs. clinton get in, then we will see Mexican-style politics for quote some time.
