I wonder what the late historian Arthur M. Schlesinger Jr. would have made of Texas Gov. Rick Perry's pandering to Lone Star secessionists on April 15. I'd love to hear what he'd say about Sarah Palin's flirtation with the Alaskan Independence Party and its disdain for the rest of the United States.
Way back in 1991, Schlesinger wrote a bestselling book, "The Disuniting of America," in which he argued that multiculturalism was threatening the integrity of the nation. "The cult of ethnicity," he wrote, culminated in an "attack" on a commonly shared American identity.
