Matt Taibbi on his new book,Insane Clown President: 

Trump is the perfect modern American. He's a human consumption machine with no attention span, no self-control, no beliefs and no hobbies outside of sex, spending, eating and talking about himself. Nixon at least played the piano and read classics. He was an intellectual with a pig's heart. Trump is just the pig part.

The distance between the two men represents how far we've fallen as a nation in the last 40 or 50 years. Once we were merely rotten and evil on the inside. Now we even lack the depth needed to be two-faced, and our dark underbelly is also our shameless, dumb exterior.

During most of the last two years I thought the Trump campaign would just be an isolated episode of mass insanity on which we would someday be able to look back and laugh. It turned out to be something a lot darker and crazier than that. Insane Clown President is the story of how we got here, to the beginning of our next long national nightmare.
