You know so much about boomers, Oneguy. What is your obsession with boomers about? Why so biased against them? They are old and dying off (maybe not fast enough for your liking). And some of them know more than you. Are they (in your worldview) responsible for all of the political ills in the world?
As far as the book having a predictable market, it doesn’t take a marketing genius to recognize that there are a large portion of Americans (more than just the Boomers that you like to malign) who want to know the details and depths of T rump’s corruption and incompetence.
Then there is the fact that in the 2016 election, persons over 45 yoa voted for T rump at 53% FOR and 44% against. Boomers went FOR T rump. And then, of course, T rump himself is a Boomer. I don’t think that he will like the book.
But maybe it is just “liberal” Boomers that you are biased against. I suppose you are fine with the proportion of Boomers who have always worked against the urges for reform.
