When articles are written about the American Enterprise Institute, space is frequently devoted to cataloguing the eccentricities of its president, Arthur Brooks.

He changed tack a few years later, earning an economics degrees by correspondence and entering academia. Now he is president of a Washington institution that is working to recast conservatism in both its practice, and its perception.
