This is the best analysis of the breakdown of the American system of government yet committed to a short form presentation.
The founding fathers were not fans of political parties, and as one can easily see for good reason. This is, however, not realistic. Our primitive hardwired tribal impulse drives like to unit with like and unlike to contest against unlike. Therefore contending political parties are inevitable until one party eventually destroys the other. Only in an idealistic world would this not be the case. And so we have come to a death struggle between a party of intellect and a party of personality.
