Who had the lowest economy as president ever in history?

RONALD REAGAN (R) 1981-1989

Explanation:

President Reagan gets an advantage in this particular ranking because the economy was doing so poorly to begin with when he took office; the EPI scored it at 76.4% in 1981. Despite what many fiscal conservatives assert, he presided over a collection of fiscally expansive policies, from defense spending to greater social welfare programs, that tripled the national debt. Combine that with a marked reduction in federal income taxes and it sounds like a recipe for disaster. However, the Federal Reserve tightening of the money supply tamed inflation and GDP growth picked up in the mid-1980s, with unemployment dropping to 5.3% by the end of his term.

The result: an EPI score of 90.8%, making his presidency the best—economically—in recent history.
