nadir of televised politics. When it was over, Americans would remember only three things about the eventual Democratic nominee, Michael Dukakis: the silly image of him riding around in a tank with an ill-fitting helmet; his flat answer when asked about the hypothetical rape of his wife; and the racially charged ad that claimed he had let a convicted killer, Willie Horton, go free on furlough. Each was an enduring image made specifically for television, the stuff of cheap drama or sitcom farce, and none had very much to do with governing the country. (It probably isn’t incidental that just over 50 percent of Americans bothered to show up at the polls on Election Day—the lowest voting rate in a presidential election in more than sixty years.)

      All of these disparate, emerging forces in the society—a vacuum in the political debate, changing ideas about morality, a new generational ethos and new technologies in the media, the tabloidization of every aspect of American life—were coming together by the spring of 1987. The vortex was spinning madly and gaining speed. If Gary Hart hadn’t been the first to get sucked into it, someone else—Bill Clinton, surely—would have found himself there before long.

      And yet, it was Hart who was about to lead the way into the modern age of political destruction, consigning himself to disgrace and infamy in the process. And this was more than a mere accident of history. If anyone had been designed to attract the vortex, to pull all of its currents together in a single violent tempest, it was Hart. On the issues of the day, Hart could see around corners with more clarity than any political figure of his time, or for some time after. But when it came to this shift in the way the society vetted its leaders, he remained disastrously, even willfully clueless.

      To his younger supporters, Hart was emblematic of the generational shift that was reshaping America—and not a moment too soon. The rebellious teens of the sixties were just now moving into middle age, with all the angst and self-absorption that had characterized their youth. (The second most popular sitcom in America, after The Cosby Show, was Family Ties, in which two former hippies struggled with their Reagan-loving teenage son, played by Michael J. Fox.) They had, in many ways, remade the popular culture already, creating an entirely new template for social justice through movies and TV, literature and music; Cosby himself was a transformational figure, drawing a huge number of white Americans into the story of the emerging black middle class. But when it came to political leadership, the Man still wasn’t getting out of the way. By the dawn of 1987, President Reagan was seventy-five (and finally starting to look it), and his main Democratic foil, House speaker Tip O’Neill, was seventy-four. Reagan’s likely successor among Republicans, George H. W. Bush, was a comparatively sprightly sixty-two. Someone had to kick open the door to Washington and let the sixties generation come rushing through. And even before his thrilling run in 1984, Hart had been first in line.

      After all, wherever politics—and Democratic politics specifically—had been headed in the two tumultuous decades before 1987, Hart had managed to lead the way. In 1969, when Hart was an unknown Denver lawyer with some ideas about reforming the electoral system, George McGovern picked him to serve on the commission that would institute the primary system for choosing Democratic nominees—an innovation that transformed presidential politics almost immediately by taking power from the old urban bosses and handing it to a new generation of activists, including women and African Americans. A few years later, McGovern, seeking to take advantage of the new primary system, tapped Hart to assemble and run his improbable, antiwar presidential campaign. McGovern overturned the party establishment on his way to the nomination (and a crushing defeat in the general election), and Hart became famous as the young, brilliant operative in cowboy boots, straddling the motorcycle of his new pal, Hunter S. Thompson.

      Hart got himself elected to the Senate just two years later, making him, at thirty-eight, its second youngest member. (Joe Biden, who got there in 1972, was six years younger.) Some older colleagues expected the glamorous ex-strategist to fashion himself as a left-wing revolutionary. But Hart was from the burgeoning West, where the party’s Eastern orthodoxies were always viewed with some contempt, and he was, by nature, too inquisitive to follow the crowd. Instead, he made a name for himself by leading the emerging movement to modernize the Cold War military. (Among those who shared his passion was a young Georgia congressman by the name of Newt Gingrich, who joined Hart’s new “military reform caucus.”) Hart’s foray into advances in modern weaponry led him, inevitably, to start thinking about the silicon chip and what it would mean for industry and education, too. Years later, Hart would remember an eye-opening lunch near Stanford with a couple of scruffy entrepreneurs named Steve Jobs and Steve Wozniak, who had recently set up a company called Apple in Jobs’s garage.

      By the early eighties, having been reelected despite the Reagan tide that wiped out nine of his Democratic colleagues (including McGovern), Hart was the front man for a small group of younger, mostly Western lawmakers whom the media dubbed the “Atari Democrats.” Their main preoccupation—which few politicians of the time understood, much less talked about—was how to transition the country and its military from the industrial economy to the computer-based world of the twenty-first century. This was dangerous ground for a Democrat in the 1980s, when industrial states and labor unions still threw around immense political power. Whenever anyone would ask Hart about whether his challenge to the status quo made him a liberal or a centrist, he would answer by drawing a simple graph on the back of a napkin or whatever else might be handy, sketching out a horizontal axis for notions of left and right, and then a vertical axis that represented the past and the future. Hart always placed himself in the upper left quadrant—progressive, yes, but tilting strongly toward a new set of policies to match up with new realities.

      This is precisely how Hart positioned himself in 1984, when his underfunded and undermanned campaign erupted in New Hampshire and swept the West—as the young, forward-thinking alternative to his party’s aging liberal establishment. “Not since the Beatles had stormed onto the stage of the Ed Sullivan Show twenty years before had any new face so quickly captivated the popular culture,” The Washington Post’s Paul Taylor later wrote of the 1984 campaign. “Indeed, the velocity of Hart’s rise in the polls was unprecedented in American political history.” Except that Hart’s youthful image belied what was, in retrospect, a critical distinction between the candidate and a lot of those who were assumed to be his contemporaries—the activists, operatives, and reporters who represented the vanguard of the boomers. The baby boom had technically commenced in 1946. Hart, on the other hand, had been born a full decade earlier, in 1936. And those particular ten years happened to make a very big difference, temperamentally and philosophically, in the life of an American.

      Those ten years meant that Hart’s essential worldview and personality were shaped more by his upbringing in the post-Depression Dust Bowl than by the beatniks or the social movements that later rocked Southern cities and college campuses. (Hart read about civil rights while doing his graduate studies in New Haven, but he never marched.) They meant that Hart, unlike his younger compatriots, didn’t see the personal as the political; to him, the personal was the personal, and nobody else’s business, and it wasn’t polite to ask too many questions. His grandfather sat silently on his front porch all day with a Bible in hand, and nobody badgered him about it. (When a neighbor finally did dare to ask what exactly he was doing out there, the old man answered: “Cramming for the finals.”) Though Hart’s father spent the war in Kansas, running through a succession of small businesses and houses, some of Hart’s uncles had returned from the Battle of the Bulge as hardened, silent men who drank too much and rode the rails for months at a time. They were his boyhood idols, and he knew better than to ask where they’d been or what they’d seen.

      Like the role models of his youth, and like the taciturn railroad men he met during his first summers in Denver, where an uncle helped Hart land a job driving spikes in the ninety-degree heat, Hart learned to value reticence and privacy. And like his political heroes, the Kennedys, Hart believed that the political arena was constructed around recognized rules and boundaries, much like the societal rules and boundaries that had governed his upbringing.
