David Brooks is taking some heat from doctrine-enforcement agents of the left and right for stating, in an interview with me at that famed redoubt of populism Le Cirque that Sarah Palin represents a "fatal cancer" for the Republican Party. Critics say that Brooks was far more blunt with me than he is in his column. At least one critic accuses him of dishonesty. It's quite the opposite, I think. David is one of the rare columnists today who wrestles with himself constantly, and who lets the public watch him change his mind. This makes him vulnerable, of course, to accusations that he is his own man. This, apparently, is a bad thing in Washington. So be it.
