No matter how you slice it, the man was an abject failure. And I'm sure he knows it, which is why he's so bitter.
One of them is that while other presidents have made striking mistakes, or allowed breathtaking mistakes to be made, none have combined virtually every type of possible mistake that positively damages America, both economically and politically, both at home and abroad, while weakening America's position in long time terms, as Carter did, while doing virtually nothing at all, of any importance at all.
and he is still doing it!
The Panama Canal giveaway alone would be disgraceful, but it was just one example in a very long list, and I have a very long memory.
I voted for that fool, and yes, I am bitter about that.
