context_page_description: 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 election winner. However, there were some close elections that it missed, such as 1948, 1976 and 2004, the popular vote in 2000 and 2016, and the likely voter numbers in 2012. The month section in the tables represents the month that the opinion poll was conducted in. D stands for the Democratic Party while R stands for the Republican Party. There were also some third parties included in some of these polls, such as the Dixiecrats and the Reform Party.
