I COVERED THIS BEFORE

The wingnuts claimed that the New Deal didn't work and that implies that deficit spending is NOT the correct way out of a recession/depression.  They point to the recession of 1937/38 as evidence but neglect to include the budget numbers. My previous response wasn't crystal clear so here's an improved version:

The recession was caused in part by the untimely decrease in Federal deficit spending, not the failure of Keynesian economics.
