This time, the blow is administered by Dan Griswold of Cato, who spoke here back in 2005. He writes here about a new book by North Dakota senator Byron Dorgan, one of those political tracts that is all about public preening and posturing, facts be damned. Dorgan is a resolute protectionist whose prescription for the pseudo-problems of the trade deficit and the declining middle class is to repeat the blunders of the 1930s.
