Carter - Stagflation.
I would rank Carter in the "Who?" range. How many incompetent 19th century presidents who stumbled through some short term fiscal problems can you name? Probably none because they just kind of disappear into history. You have to really screw up like Hoover (who started down the high-tax big spending path Roosevelt followed) in order to be remembered for fiscal problems.
LOL! Carter should thank Reagan that he is not remembered as another Hoover...
