Check out Andrew Sullivan's review in the New York Observer (
temporary link). Blumenthal is a power worshipper. Having started on the leftist fringe, he was bowled over by the possiblity of achieving political power that Clinton offered. He has a manichean view of political life: he believes the enemy is evil and every tactic is justified if it helps him win. The vein of feline sarcasm that's so noticeable in Sidney's work helped to armor him for combat. Sullivan dissects him well, but seems to backslide a little on the Clinton impeachment.
