Biden got it all wrong. The stock market crashed in 1929 and Hoover was President. Television was not in use in homes until the 1950's. FDR who was elected in 1932 talked to the nation by radio.
Maybe Biden is not ready for the office of Vice President. Biden can get facts so wrong and no one blinks an eye. No columnist are calling for his resignation. Comics are not mocking him. What would be the response if Sarah Palin had said this?
