People dislike Carter for the Iran hostage situation, and I think there was also a fuel crisis which might have been related.
I wouldn't attack Reagan's foreign policy as a whole, but it was a dirty trick to convince the Iranians not to release the hostages before the election.
Tricky Dick also made an election deal with the North Vietnamese. And I also think Nixon did some good things as well, for example he founded the EPA.
People need to learn context, from a source other than the propagandists.
Nixon's "shock doctrine" (1971) is what triggered both the runaway inflation and the oil crises (note plural -- it began in 1973). Both of those infected the terms of both Ford and Carter and both of them paid for it The Iran hostage thing goes back to the meddling of the Dulles Brothers who sent the CIA to overthrow a democratically elected prime minister and install a Shah that the country resented. The Shah's ejection was the chickens coming home to roost from that ill-advised venture. Without the Nixon Shock the inflation and the oil conundrum probably don't happen, and without the Dulles meddling nor do the hostages.
So the oil thing is born in 1971 and the hostages, 1953. Yet Nixon and Eisenhower somehow get to watch Carter get pinned with them as if they just magically appeared out of nothing. Poof.
