Sidney M. Milkis reviews Senator Byrd’s Losing America, his diatribe against Bush’s Iraq policy and especially against Congress’ too swift enactment of the Iraqi resolution and in favor of a greater role for Congress in foreign policy. In the best light, Milkis argues, Byrd urges us to reconsider the debate between Madison and Hamilton on presidential authority. Milkis moderates Byrd’s thesis by showing that Senator Kerry agrees with Bush on the power of the presidency in the conduct of foreign policy (Kerry even agrees with Bush on the doctrine of preemption, it should be noted).
