Senator Biden says today’s leaders should take a lesson from the history books and follow fellow Democrat Franklin D. Roosevelt’s response to a financial crisis. “When the stock market crashed, Franklin D. Roosevelt got on the television and didn’t just talk about the, you know, the princes of greed. He said, ‘Look, here’s what happened,'” Senator Obama’s running mate told the “CBS Evening News.” Except Republican Herbert Hoover was in office when the stock market crashed in October 1929. There also was no television at the time; TV wasn’t introduced to the public until a decade later, at the 1939 World’s Fair.
