We’re posting about two new interviews per week on Between the Covers. Today, we have Donald Critchlow, talking about his book The Conservative Ascendancy. Earlier this week, it was Allen Guelzo, author of Lincoln and Douglas–this year is the 150th anniversary of those famous debates. There’s also David Anderegg on Nerds, Derbyshire star inventor Robert Ferrigno on his novel Sins of the Assassin, Brad Birzer on Christopher Dawson, and Thomas Sowell on Economic Facts and Fallacies. Plus loads more. Listen here on NRO or subscribe to the series via iTunes.
