WASHINGTON (AP) — Calling Donald H. Rumsfeld energetic was like calling the Pacific wide. When others would rest, he would run. While others sat, he stood. But try as he might, at the pinnacle of his career as defense secretary he could not outmaneuver the ruinous politics of the Iraq war. Regarded by former colleagues as equally smart and combative, patriotic and politically cunning, Rumsfeld had a storied career in government under four presidents and nearly a quarter century in corporate America. The two-time defense secretary and one-time presidential candidate died Tuesday. He was 88.
