Presidential economics: Do parties matter? A look at GDP, employment, CPI, and other statistics

Though the picture so far is of the Republicans as the party of austerity and the Democrats as the party of stimulus, there's a surprise when it comes to changes in the federal deficit: Republicans are more liberal with the red ink than Dems. On average, a Republican in the White House has meant a shift of –1.9% of GDP in the government's budget balance (i.e., towards smaller surpluses or bigger deficits), while a Dem has meant a 1.5% improvement in the budget position (or 1.8%, if you start in 1949, thereby omitting the huge World War II deficit). And in this case, the average is a faithful representation of the distribution, with only one Democrat in the minus column and only one Republican in the plus.
