Brinkley is highly overrated as a historian. As I recall, he made a lifetime loser named John Kerry into some kind of General Eisenhower instead of revealing his parasitic life style, as a liar and possible Logan Act violator during a time of war.
That is why Kerry was named after a toilet - he’s always been full of crap and covered up by used toilet paper known as the print media.
