I read this book about 10yrs ago. Finding it so well researched and instructive, I recommended it to all my family and friends. It pretty much opened w/ the 1917 Bolshevik Revolution. Because I’d been a professional Worldwide stamp dealer for over 50yrs (Philatelist), I was fairly well versed in world history. Professor Paul Kengor neatly tied up most of my suspicions of where this Country was headed: a direct line to Marxism/Socialism. Beginning with the Little Red Church in Wash. State attended by Barack Obama’s Grandparents ; followed with Obama’s Communist mentor: news paper columnist Frank Marshall Davis, and ending in Hawaii at the exclusive Punahou College Prep. High School. The whole background on Obama, parents, grandparents and associates is well covered in Dupes. An important read for teens through adulthood.
