I thought President Carter was an incompetent liberal but I don't recall ever thinking he hated the United States and wanted to "fundamentally change" it into something else. Sure, President Carter blamed the American people for some of his shortcomings but he also was able to accept at least a modicum of responsibility.
President Carter was not, in any way I could see, a racist. President Carter did not attempt to eliminate the 1st Amendments guarantee of freedom of religion. President Carter did not attempt to eliminate the 1st Amendments guarantee of freedom of speech. President Carter did not, to the best of my knowledge, use the IRS and other liberal-headed departments in government as shock troops to attack his "enemies."
I think the similarities are more in results than in the two individuals.
