One of the highest words of praise that could come to a Washington Post reporter from Ben Bradlee when he was executive editor was the hearty phrase, "You're all over the paper!" Well, I guess I'm all over U.S. News this week. I wrote the cover story on American presidents at war and also a column on today's less than pretty politics. I can take a breather now: The current issue is on the stands for two weeks. My thanks to the editors for allowing me to write the cover story, which required some very enjoyable research.
