By what measure? Can you source that claim?
“Since World War II, according to many economic metrics including job creation, GDP growth, stock market returns, personal income growth, and corporate profits, the United States economy has performed significantly better on average under the administrations of Democratic presidents than Republican presidents.”
Reagan was the only Republican that reduced unemployment by a little bit, but he was in the lower half of presidents who did that. But he failed to increase employment significantly, he increased the deficit significantly, and he did damage with the bunk feed-the-rich “Trickle Down” theories.
Even Trump agreed. “During a March 2004 interview, Trump stated: ‘It just seems that the economy does better under the Democrats than the Republicans.’”
