The U.S. economy has just posted an impressive 5.9% jump in Q4 GDP growth, less than a year after Obama inherited an economy in freefall. Also, the Dow Jones jumped 29.5% in Obama's first year, the third-best performance of any president. (The top two honors also go to Democrats, FDR's 96.5%, albeit starting from a post-Crash low; and Harry Truman's 30.9%.) The average change in the Dow in the president's first year is +24% for Democrats, -1% for Republicans. The GOP, of course, has for decades enjoyed the reputation for superior management of the economy. Yet for a century the U.S. economy by a wide margin has performed better during Democratic presidencies. Go figure.
