Since the Second World War, the economy has done better when Democrats are in the White House, a point that Hillary Rodham Clinton made in response to a question from CNN's Anderson Cooper.
"The economy does better when you have a Democrat in the White House and that's why we need to have a Democrat in the White House in January 2017," the former secretary of state said.
The average rate of economic growth under Democratic presidents since the Truman administration has been 4.4 percent, compared to 2.5 percent under Republicans. The economy has performed better on other measures under Democratic presidents, too. Industrial production, unemployment and returns on the stock market have all been worse when a Republican occupies the Oval Office.
It is unclear, though, whether Democrats' approach to the economy is responsible for this impressive record, or whether they just got lucky. All kinds of factors affect the economy that are beyond the president's control -- wars, oil shortages and the decisions of the Federal Reserve.
