Ronald Regan Quadroupled the US National Debt.

"Economist Mike Kimel notes that the five former Democratic Presidents (Bill Clinton, Jimmy Carter, Lyndon B. Johnson, John F. Kennedy, and Harry S. Truman) all reduced public debt as a share of GDP, while the last four Republican Presidents (George W. Bush, George H. W. Bush, Ronald Reagan, and Gerald Ford) all oversaw an increase in the country’s indebtedness.[2] Economic historian J. Bradford DeLong, former Clinton Treasury Department official, observes a contrast not so much between Republicans and Democrats, but between Democrats and "old-style Republicans (Eisenhower and Nixon)" on one hand (decreasing debt), and "new-style Republicans" on the other (increasing debt).[3][4] Similarly, David Stockman, director of the Office of Management and Budget under President Ronald Reagan, as op-ed contributor to the New York Times, blamed the "ideological tax-cutters" of the Reagan administration for the increase of national debt during the 1980s.[5]"

All this because these new-style Republicans violate the scinece Keynesian Economics
