Did you remember the late Lawrence McDonald, a Democrat from Georgia? He was also another great American who was killed by the Soviets when they shot down the KAL flight in 1983. I only wish there were more like him.
Yes, you're right, there were sane Democrats in previous times, including Sam Nunn. I was thinking of current members, so I was stuck with Zell Miller, Joe Leiberman, and Evan Bayh.
