The Big Lie

George W. Bush, speaking at Greece Athena Middle and High School, Greece, New York, May 24, 2005:

See, in my line of work you got to keep repeating things over and over and over again for the truth to sink in, to kind of catapult the propaganda.

Or, as someone else put it a few years ago:

If you tell a lie big enough and keep repeating it, people will eventually come to believe it.

Joseph Goebbels
