Colorado’s Democratic US Senator Gary Hart lost his party’s presidential nomination in 1984… but four years later, he looked like a winner. Then the Miami Herald investigated a rumor that turned out to be true, that Hart was having an extra-marital affair with a young, blonde named Donna Rice. Hart quit the campaign, and he’s most often remembered for the picture of Donna Rice on his lap on the deck of a yacht called “Monkey Business.” That’s the heart of a new book on what Hart’s demise meant for political journalism. It’s All the Truth is Out by Matt Bai, formerly of the New York Times, now with Yahoo!.
