Richard M. Nixon Campaign Button, 1972

President Richard Nixon touted his foreign and domestic policy achievements in his 1972 reelection run. "Nixon Now" -- the Republican campaign slogan -- urged voters to reelect the president. They did in a landslide. Popular support waned however when news leaked out about White House involvement in the cover-up of the Watergate break-in. Two years after his landslide victory, the president was forced to resign.
