I couldn't help but conclude after reading this article that there appears to be a tinge of jealousy within the New York Times over the rapid success and never-say-die attitude at Politico.
Sure, the reports that Politico's management works its people hard (and therefore turns over at a perhaps higher than typical average) are valid, but I would also ask you to think about which news organization you are more likely to turn to in order to grasp what is happening right now in national politics.
Frantic and fatigued? Sure. But the industry leader? If it's not, Politico is certainly in the discussion.
