How much James Carville and Mary Matalin can you stomach? HBO is betting that you haven't had enough of these cantankerous spinmeisters and they've given them their own show. It's not TV. It's K Street, the cable network's weekly semi-reality show from George Clooney. K Street? Isn't C-SPAN enough for the political junkie set? Lawyers and wonks have taken over every other aspect of American life, do they need to take over TV also? Previews of the show have been hammered for liberal political bias (what a surprise) but what's really irritating is more glamorization of the ugly, banal, and amoral world of politics in DC.
