Carter ran our economy into the ground. He inherited a booming economy and drove it into the ground:
1976 5.4%
1977 4.6%
1978 5.6%
1979 3.2%
1980 -0.2%
Fed raised rate to 20%. GDP dropped 7.9% in Q2. Fed lowered rate to 10% by August to boost economy, then raised it to 20% to fight 12.5% inflation. Iran oil embargo.
Carter's Presidency is best summed up in two words: Misery Index.
But luckily for Carter, no one calls him the Worst President Ever anymore. Not since Obama.
