According to Ohio Republican Congress-critter Steve Austria, FDR caused the Great Depression:
When [President Franklin] Roosevelt did this, he put our country into a Great Depression. He tried to borrow and spend, he tried to use the Keynesian approach, and our country ended up in a Great Depression. That’s just history.
Unfortunately for the Republican version of history, the Great Depression was kicked off by the stock-market crash in 1929, when Hoover was President. FDR became President in 1933. As BoingBoing posits, maybe FDR was a “time-traveling socialist”?
