Carter?

He was as lame as you could pick for a President.
And a screw up, because he was a micro manager.

Carter gets the award for President who kept the best track
of who was using the white house tennis court!

Of those listed, only Reagan is noteworthy. Clinton's "success"
was entirely due to a Republican Congress.

Unlikely... probably Clinton, Reagan, or Nixon. Even LBJ was
better. Carter will win for the best ex-pres.

In the future historians will rate GWB as one of the best presidents
we've ever had.
