At a 1988 campaign event, Frank Fahey, a New Hampshire high school teacher, asked Sen. Joseph R. Biden, Delaware Democrat, about his law school performance. An irritated Mr. Biden responded that he probably had a higher IQ than Mr. Fahey and that he had earned three degrees as an undergraduate, gone to law school on a full academic scholarship and finished in the top half of his class — none of which turned out to be true. Mr. Biden later dropped out of the presidential race.
