You know, it's so easy to look down on Nixon. Why not try some disdain for somebody harder to dislike?
What you mean he should get a pass for running on a platform for getting out of the Vietnam War (his "secret" plan of 1968) and then expanding the war, invading Cambodia, support of Pinochet, his abuse of domestic power and his administration being a training ground for the senior Bush administration asshats (Cheney & Rumsfeld being most prominent). Sure, if you focus on his lack of charisma it's a bit shallow. But when you look at his actual career, he really deserves the scorn.
