Polling for United States presidential elections (original) (raw)

Gallup was the first polling organization to conduct accurate opinion polling for United States presidential elections. Gallup polling has often been accurate in predicting the outcome of presidential elections and the margin of victory for the winner. However, it missed some close elections: 1948, 1976 and 2004, the popular vote in 2000, and the likely-voter numbers in 2012. The month section in the tables represents the month in which the opinion poll was conducted. D represents the Democratic Party, and R represents the Republican Party. Third parties, such as the Dixiecrats and the Reform Party, were included in some polls.
