Never subtle, always scary, Patrick Buchanan remains a pudgy-faced tour de force of right-wing, fire-and-brimstone pomposity. In his new book, The Death of the West: How Dying Populations and Immigrant Invasions Imperil Our Country and Civilization, Buchanan argues that the tragedies of Sept. 11 should alert Americans to the danger of our foreign-born neighbors. “Uncontrolled immigration threatens to deconstruct the nation we grew up in and convert America into a conglomeration of peoples with almost nothing in common…” writes Buchanan. His solution? Close the borders. Repent before God. And throw the liberal politicians back to the marijuana patch that spawned them. Buchanan’s power arises from his rhetorical sorcery: With the wave of a pasty white finger, he can transform peoples’ seemingly innocent nostalgia for old-fashioned rural America into a vicious argument for political and cultural exclusion. Sadly, many fail to resist his spell. Hear Buchanan at 7 p.m. at Olsson’s Books and Records, 1200 F St. NW. Free. (202) 347-3686. (Felix Gillette)
