IN case you missed it, our nation’s officeholders, current and former, have been working overtime to make us proud.  Ted Cruz threw a histrionic hissy fit in front of Arab Christians. Sarah Palin went to a birthday party where her family reportedly got into a brawl. Mark Sanford emitted a self-pitying aria of romantic angst. Debbie Wasserman Schultz compared some Republicans to wife beaters.  Somewhere in there, I sank into a newly deep funk about the kinds of people drawn to politics these days.  Then I burrowed into Matt Bai’s new book and I hit rock bottom.  It’s called “All the Truth Is Out,” it will be published later this month and it’s about Gary Hart. Remember him: the presidential contender who rode a boat named Monkey Business into a media whirlpool? You should, as the book, which is excerpted in The Times Magazine this weekend, makes clear.  And the reason isn’t so much the scandal that swallowed him or his particular exit from the political arena. It’s the warning that his story sounded — about a new brutality on the campaign trail, about uncharted frontiers of media invasiveness and about the way both would wind up culling the herd, not in favor of the strongest candidates but in favor of those so driven or vacuous that the caress of the spotlight redeems the indignities of the process.  Has running for public office become less attractive than ever? Does it frighten off potential leaders who might benefit us and clear a path for aspirants with less to offer?  Bai’s book suggests as much, and he points a finger at political journalism, which, he writes, is “now concerned almost entirely with exposing lies and unearthing character flaws, sexual or not.”  “Hart’s downfall,” Bai continues, “was the thing that tipped the scales completely, the catalyst that made it O.K. — even necessary — for all aspiring political reporters to cast themselves as amateur P.I.s and psychotherapists. If post-Hart political journalism had a motto, it would have been: We know you’re a fraud somehow. Our job is to prove it.”  “All the Truth Is Out” has fascinating tidbits, in particular about friendships that bloomed between Hart and Mikhail Gorbachev and Hart and Bill Clinton, his descendant in the annals of sexual scandal.  It also has a few belly laughs — painful ones. Bai writes that when the media was consumed by Hart’s sex life, Johnny Carson joked that “the nomination would fall into Hart’s lap — if there was any room left there. On the highly rated sitcom ‘Golden Girls,’ one of the little old ladies commented of another character, ‘She’s Gary Hart’s campaign manager. It doesn’t pay much, but you don’t have to get out of bed to do it.’ ”  Those jokes serve a point: Hart was reduced to a single trait, and everything else he had to say was muffled by it. And the same questionable fate befell many politicians after him, as privacy perished and the media’s insistence on a certain sort of juicy narrative intensified.  “It’s just getting worse,” Stuart Stevens, the veteran Republican strategist who spearheaded Mitt Romney’s 2012 presidential campaign, told me. “It’s the most grueling process imaginable.”  As CNN’s Peter Hamby noted in a study he wrote during a fellowship at Harvard last year, the accelerated news cycle of the social-media age demands meaningless scoops, trumpets dubious gaffes and turns the reporters trailing a candidate into “one giant, tweeting blob.”  That blob suffocates its quarry, often at the prodding of his or her rivals, who supply opposition research (or “oppo”) that strays from serious byways down silly cul-de-sacs. This was captured in a story about the Senate elections that was splashed across the top of the Politico website Friday afternoon.  The headline blared, “GOTCHA! How oppo took over the midterms.” And the story began, “Why would anyone want to talk about immigration, terrorism, gun control or the national debt, when there’s Alison Lundergan Grimes’ bus, John Walsh’s thesis, Bruce Braley’s chickens and Pat Roberts’ recliner? Gotcha stories — ranging from those tangentially related to issues of the day to the completely ephemeral and even absurd — have been front and center in an abnormally large number of top races this year.”  Everything’s a teapot, primed for a tempest. Although Joe Biden has a famously spastic tongue and there’s no reason to believe he is anti-Semitic, he makes an indecorous reference to “Shylocks” and the outrage machinery cranks into gear. The content-ravenous blogosphere lights up.  BUT the hysteria of the present media climate isn’t the only problem or turnoff. There’s the extended duration of a political race. There’s the ceaseless fund-raising, the burden of which was spelled out in an internal memo that leaked from Michelle Nunn’s Senate campaign in Georgia. It decreed that drumming up money should consume 80 percent of her time in the first quarter of 2014, declining to 70 percent in the third.  The memo identified Jews as a “tremendous financial opportunity,” so long as Nunn struck the right position on Israel, still to be finessed. Ah, the heartfelt conviction that animates today’s candidate!  Writing about the memo in The Times Magazine, Mark Leibovich said that his main takeaway was “that a political campaign today is a soul-killing pursuit.” He presumes a soul to take.  Seriously, who’s attracted to this ordeal? Some people with only the best intentions and motivations, yes. But also plenty like Sanford, whose 2,346-word Facebook post about his postmarital woes signaled a Newt-caliber neediness. Or like Wasserman Schultz, an intemperate warrior who, if Politico’s profile of her last week got it right, is consumed by self-centered ambition. Or like Cruz, with his lust for attention, even if it’s negative.  Or like Palin. She’s clearly on Bai’s mind when he writes that the “post-Hart climate” of estrangement between politicians and the press — and of shallow campaign pageantry — made it easier for candidates with little policy expertise or insight into governance, because no one expected any candidate to say anything too detailed or deep.  “A politician could duck any real intellectual scrutiny simply by deriding the evident triviality of the media,” Bai writes.  It’s odd and funny that the conservative writer Charles Krauthammer sought to vilify President Obama last week by calling him, of all things, a narcissist. When this came up on “The View” and narcissism was explained to Rosie O’Donnell as “a mental disorder in which people have an inflated sense of self and their own importance and a deep need for admiration,” she replied, “That’s every celebrity I know, including me.”  It’s a lot of politicians, too. The process guarantees it.
Our political process repels many leaders who might do us good and leaves us with a sometimes motley crew.
