I'd rank Carter so low he wouldn't even make the list (Like #43 on the list of 42!). Even today the thought of living through Carter's Presidency sends shudders through me. JFK really doesn't belong on the list since his Presidency was cut short by his assassination. I don't know why people are so hot about LBJ, I always thought his mis-management of the Vietnam war should have ranked him just above Carter's.
I'd Rank President Reagan at least #5, though I've always had a sneaking admiration for Truman. And I'd definitely agree with more than a few of you who feel that Nixon got a "Raw Deal", and probably over time that will change. Despite his shortcomings, Nixon knew politics, especially foreign relations, and he deserves better.
C#133 on Truman...
