Conservative columnist Robert Novak died this morning after a battle with brain cancer, reports the Chicago Sun-Times, for which he has been a columnist since 1966. The Washington Post has a lengthy piece detailing the conservative columnist's national prominence. Perhaps what will be missed most about Novak, even more than his journalistic skill or the weight of his commentary, is his demeanor: the scowling "prince of darkness" antithesized the exuberance and chumminess that have become standards of TV news and commentary today. With Novak gone, who is left to scowl?
