Jacob Heilbrunn on Andrew Sullivan:
There are many figures on the present stage who epitomize this slide, but none better than Sullivan. The critic Lee Siegel asserted in Harper’s in 2001 that Sullivan’s mental clutch slipped after the September 11 attacks, when he had written that the left in its “enclaves” posed the threat of a “fifth column.” Siegel ridiculed the notion that “the scattered lunacies of the Chomskyan left, out of whose pathetic powerlessness [Sullivan] has constructed a threat to national security,” rose to the status of a fifth column. In any case, as the war in Iraq faltered and questions of torture by U.S. troops and authorities arose, Sullivan jumped ship and declared that conservatism had lost its way. By November 2006, Sullivan was asserting that President Bush, whom he had previously praised as a new Churchill, had “lost his mind.” He has since moved on to penning fawning tributes to Barack Obama’s presidential candidacy.
Sullivan is not the topic of Heilbrunn's article. It's just a very accurate shot. The actual topic is the curious creature known as the public intellectual, who suffers today in comparison to those of the past. The entire piece is worth your time.
