It didn't seem that way in the broadcast version, but Jon really kicks the crap out of her in Part 3. You really need a strong stomach to get through it all.
UPDATE 10:14am, Pacific:
James Fallows of the Atlantic Monthly wrote a profile of Betsy McCaughey (Jon's victim in the video below) a week or two ago. But this is the money quote:
I have been far too soft on Betsy McCaughey. Even when conferring on her the title of "most destructive effect on public discourse by a single person" for the 1990s. She is way less responsible and tethered to the world of "normal" facts and discourse than I had imagined.
