If you haven’t read Tim Dickinson’s terrific article on the genius/lunacy of Roger Ailes, the chairman of Fox News, in the new issue of Rolling Stone, it’s a must-read, tour-de-force bit-o-journalism. Dickinson manages to make sense of the entire wacko-conservative gestalt of Fox News: It’s a top down organization of far-right toadies—no liberals need bothering applying—each vying for attention, approval and career advancement—natch—from the power-mad, brilliant yet crazy-seeming paranoiac who runs that bughouse.

Here are three key “takeaway” paragraphs from the article:

Ailes begins each workday buffered by the elaborate private security detail that News Corp. pays to usher him from his $1.6 million home in New Jersey to his office in Manhattan. (His country home – in the aptly named village of Garrison – is phalanxed by empty homes that Ailes bought up to create a wider security perimeter.) Traveling with the Chairman is like a scene straight out of 24. A friend recalls hitching a ride with Ailes after a power lunch: “We come out of the building and there’s an SUV filled with big guys, who jump out of the car when they see him. A cordon is formed around us. We’re ushered into the SUV, and we drive the few blocks to Fox’s offices, where another set of guys come out of the building to receive ‘the package.’ The package is taken in, and I’m taken on to my destination.”Ailes is certain that he’s a top target of Al Qaeda terrorists. “You know, they’re coming to get me,” he tells friends. “I’m fully prepared. I’ve taken care of it.” (Ailes, who was once arrested for carrying an illegal handgun in Central Park, now carries a licensed weapon.) Inside his blast-resistant office at Fox News headquarters, Ailes keeps a monitor on his desk that allows him to view any activity outside his closed door. Once, after observing a dark-skinned man in what Ailes perceived to be Muslim garb, he put Fox News on lockdown. “What the hell!” Ailes shouted. “This guy could be bombing me!” The suspected terrorist turned out to be a janitor. “Roger tore up the whole floor,” recalls a source close to Ailes. “He has a personal paranoia about people who are Muslim – which is consistent with the ideology of his network.”

Murdoch installed ailes in the corner office on Fox’s second floor at 1211 Avenue of the Americas in Manhattan. The location made Ailes queasy: It was close to the street, and he lived in fear that gay activists would try to attack him in retaliation over his hostility to gay rights. (In 1989, Ailes had broken up a protest of a Rudy Giuliani speech by gay activists, grabbing demonstrator by the throat and shoving him out the door.) Barricading himself behind a massive mahogany desk, Ailes insisted on having “bombproof glass” installed in the windows – even going so far as to personally inspect samples of high-tech plexiglass, as though he were picking out new carpet. Looking down on the street below, he expressed his fears to Cooper, the editor he had tasked with up-armoring his office. “They’ll be down there protesting,” Ailes said. “Those gays.”

Ailes knows exactly who is watching Fox News each day, and he is adept at playing to their darkest fears in the age of Obama. The network’s viewers are old, with a median age of 65: Ads cater to the immobile, the infirm and the incontinent, with appeals to join class action hip-replacement lawsuits, spots for products like Colon Flow and testimonials for the services of Liberator Medical (“Liberator gave me back the freedom I haven’t had since I started using catheters”). The audience is also almost exclusively white – only 1.38 percent of viewers are African-American. “Roger understands audiences,” says Rollins, the former Reagan consultant. “He knew how to target, which is what Fox News is all about.” The typical viewer of Hannity, to take the most stark example, is a pro-business (86 percent), Christian conservative (78 percent), Tea Party-backer (75 percent) with no college degree (66 percent), who is over age 50 (65 percent), supports the NRA (73 percent), doesn’t back gay rights (78 percent) and thinks government “does too much” (84 percent). “He’s got a niche audience and he’s programmed to it beautifully,” says a former News Corp. colleague. “He feeds them exactly what they want to hear.”

Fox News will make a lot more sense after you’ve read this article. You’ll be simultaneously impressed and sickened by the evil genius of Roger Ailes. Love ‘em or loathe him—I’m firmly in the latter category I can assure you—it cannot be denied what a media-manipulating genius he truly is.
