Bruce Montgomery's latest book takes on the extraordinary doubletask of placing Cheney's expansion of the powers and authority of the office of the vice presidency in a historical context, as well as tracing the development of Cheney's peculiarly absolutist conception of executive power. Montgomery succeeds on both counts. The real strength of the book, setting it apart from the laudable account of Barton Gellman's Angler, is its historical perspective, which successfully interweaves two analytical narratives.
