I'm a huge Carter guy. But Carter's weaknesses did him in.
He had a democratic congress on his watch, but still couldn't build up any type of relationship with congress to get support. And since he started to look weak to the democratic party, Ted Kennedy came on strong, making the primary a tough one for him, where the democratic party was split. He went in against regan without a chance in hell. He supporters had already deserted him, and even some democrats voted for Regan.
Him giving away the Panama Canal was proof that his Foreign Policies were shite, bro.
Carter was a great president in his own right, but as far as FP, War, etc. He was weak in that area,
