Dupes exposes the legions of liberals who have furthered the objectives of America’s adversaries. Kengor shows not only how such dupes contributed to history’s most destructive ideology—Communism, which claimed at least 100 million lives—but also why they are so relevant to today’s politics. Packed with stunning revelations, Dupes shows in frightening detail how U.S. adversaries exploit the American home front. Now with an updated introduction to the paperback edition.
