A provocative (and potentially defamatory) profile of Marcos Moulitsas, the self-admitted "asshole" proprietor of the Daily Kos blog. The comparison of Kos with Bill James is an apt one, although I think the Old Guard he's challenging isn't the punditocracy (that battle is being fought by the likes of Atrios, Kevin Drum, Steve Gilliard, et al.) , but the politocrats within the Democratic Party, as well as the adherents to the increasingly obsolete "grassroots" model used by progressives since the 1960's. Kos treats political advocacy as something more than a hobby to be pursued every election night, and the country owes him a debt of gratitude for the unexpected partisan feistiness of the Democratic Party, only a year after one of its most devastating losses.
