Scott Adams is a washed-up cartoonist turned reactionary collaborationist pundit whose only recent accomplishment is getting owned on Twitter all day. What does he know about persuading people?
Regardless, American media makes for an abysmal benchmark.
He also doubled-down - with qualifications - once Trump secured the nomination. Almost everyone else - including myself - saw the general election as a Clinton shoo-in, given Trump's numerous deviations from what most of us had believed were political candidate social norms, among other apparent disadvantages.
I wouldn't say he has insight to American but rather human psyche and its biases, which you should know if you've read his articles.
