An interesting insight from This Town, by Mark Leibovich, pg 278-279. It would presumably be near impossible for a website like Politico to maintain its level of output without resorting to processes like this:
Sure enough, a few days later, Politico’s founding editor, John Harris, went on a new enterprise called “Politico TV” and revealed that that is exactly how the “stupid” story came about. “A lot of people’s stories generate from people’s rants,” Harris explained. “Alex Burns wrote up one of my rants.” Burns made some phone calls to prove—or “explore”—his boss’s premise that voters were stupid. Lo and behold, the premise came back rock solid.
