Here's something your third-grade teacher never taught you: Ben Franklin won the American Revolution by seducing French women. The years of battles between British and French-allied American soldiers, Cornwallis's surrender at Yorktown in 1781—those were cheap parlor tricks meant to occupy lesser-hung men, or so argue Hustler publisher Larry Flynt and historian/political junkie David Eisenbach in their new book, One Nation Under Sex. Tonight, Eisenbach and Flynt will be on hand to discuss a history's worth of presidential sex scandals that changed politics, the juicy stuff generally whitewashed for school-age audiences.
