Eisenhower was the last fiscally conservative republican president. Republicans like to talk about LBJ as a big spender, but every republican president since Johnson has been a bigger spender than LBJ was.
A comparison of government spending and the annual federal deficits accumulated since 1960 under republican presidents and under democratic presidents shows that republicans are bigger spenders and run much larger deficits than democrats. Bush has been about average as a big spender for republican presidents. If Bush was a democrat he would be the biggest spending democrat since WWII.
Of the slightly more than $4.2 trillion in accumulated deficits since 1960, more than $3.9 trillion has been accumulated under republican presidents while only about $250 billion has been accumulated under democratic presidents. And of the 15 times since 1960 that the annual deficit has exceeded 3% of GDP, every single time it was under a republican president. In that time the annual deficit has never exceeded 3% of GDP under a democratic president.
