"The Revolt of the Public" was published before Trump started his political career but captures many of the issues that helped him reach the Oval Office.

Some good tidbits like the Iowa reporter who said
“We’re beating the shit out of the guy, and he just won’t die.”
or
a story about "Rathergate" - M5M humiliation by an individual.

I don't know what is behind the paywall but what I see is a good read.
