With the speculation that Obama might choose former Georgia Senator Sam Nunn as his running mate to shore up his national defense credentials, it might be worth taking a look back to when Nunn got his undeserved reputation as a "tough" Democrat on foreign policy. Back in the 1980s, he moved noticeably to the left when he pondered a possible run for president in 1988, especially on the issue of the ABM Treaty interpretation, where he wanted us to concede to the Soviets’ (late) narrow interpretation (after years during which the Soviets wanted the broad interpretation when it favored their missile defense research). Then Nunn rigged to the right (sort of) in opposing the INF Treaty in early 1988.
Reagan took note of Nunn several times in his diary. March 23, 1988: "On INF, San Nunn, a highly overrated senator, is kicking a tantrum which could cause trouble getting it ratified."
Sept. 14, 1988: "Sen. Nunn has become a real pain. He’s acting as if he’s the supreme authority on defense matters."
On still another occasion, Reagan wrote of congressional Democrats (without mentioning Nunn by name): "They are actually sitting on the Soviet side of the negotiating table."
