Kinsley does the math

Michael Kinsley compares Republican presidents and Democratic presidents on economic numbers since 1960.
His results?

It turns out that Democratic presidents have a much better record than Republicans. They win in a head-to-head comparison in almost every category. Real growth averaged 4.09% in Democratic years, 2.75% in Republican years. Unemployment was 6.44%, on average, under Republican presidents, and 5.33% under Democrats. The federal government spent more under Republicans than Democrats (20.87% of GDP, compared with 19.58%), and that remains true even if you exclude defense (13.76% for the Democrats, 14.97% for the Republicans).

What else? Inflation was lower under Democratic presidents (3.81% on average, compared with 4.85%). And annual deficits took more than twice as much of GDP under Republicans than Democrats (2.74% of GDP versus 1.21%). Republicans won by a nose on government revenue (i.e., taxes), taking 18.12% of GDP, compared with 18.39%.

How about starting with the Reagan years, the so-called "rebirth" of Republicans:

But doing all the same calculations for the years 1982 through 2002, and giving each president's policies a year to take effect, changes only one result: The Democrats pull ahead of the Republicans on per capita personal income.
