Peggy Noonan is a great ally and a doubtful foe. She turned, mildly, on Reagan. She has turned on Bush. So what. Her human insights are wonderful, her writing , usually, excellent. She is setting up her pick for 2008 awkwardly. Bush supporters and detractors, alike, have made much of Ms. Noonan’s Friday Opinion Journal column about President Bush. As a fan Peggy’s, I was disappointed. One of the hallmarks of conservatism—something that should distinguish us from them—is that we don’t eat our own in public.
