No less disconcerting was a still-unexplained passage of Palin’s convention speech: Her use of an unattributed quote praising small-town America (as opposed to, say, Chicago and its community organizers) from Westbrook Pegler, the mid-century Hearst columnist famous for his anti-Semitism, racism and violent rhetorical excess. After an assassin tried to kill F.D.R. at a Florida rally and murdered Chicago’s mayor instead in 1933, Pegler wrote that it was “regrettable that Giuseppe Zangara shot the wrong man.” In the ’60s, Pegler had a wish for Bobby Kennedy: “Some white patriot of the Southern tier will spatter his spoonful of brains in public premises before the snow falls.”

This is the writer who found his way into a speech by a potential vice president at a national political convention. It’s astonishing there’s been no demand for a public accounting from the McCain campaign. Imagine if Obama had quoted a Black Panther or Louis Farrakhan — or William Ayers — in Denver.
