National Review loves Donald Rumsfeld; doesn’t care for Christopher Buckley or Jeffrey Hart.
Perhaps because so many of its founding editors were erstwhile Stalinists and Trotskyists, the editors of National Review have always had a propensity for purges, ideological house-cleanings that involve black-balling those who don’t follow the party line. Some of these purges have been entirely justified: the conservative magazine did well to kick out kooks like Revilo Oliver and the Birchers in the early 1960s. And good riddance to the Randians as well. Other purges have been regrettable: anti-war libertarians were a strong presence on the American right till National Review started boycotting them. It would have been nice if those anti-war voices had remained part of the conservative conversation.
Now the magazine seems to be going through another one of its periodic ideological civil wars, kicking out anyone who might have a kind word to say about Barack Obama. As has been widely discussed, Christopher Buckley, son of founding editor William F. Buckley, lost his column in the magazine after he wrote an endorsement of Obama (an article that ran in another publication, The Daily Beast).
