You know, anything more negative, anything more disparaging, anything more adversarial than what [Donald Trump] does already. The mystery is how he's gotten as far as he's gotten.

People like nonfiction presented to them in a certain way, so that they don't have to think about whether it's true or not. They like it to have that imprimatur of respectability, of genuineness.
