The ex-president may be selling off the criminal justice system but Mary McGrory has her eye on the ball. “President Bush, in his first White House news conference, proudly observed that he is making progress in encouraging a more “civil discourse.” Perhaps, but more grammatical it ain’t — not when Bush is doing the talking. It’s scandalous, especially for a man who purports to be the “education president.” What happened to his own?” Good try, Mary. No score.
