During the 2020 Democratic Presidential Primary, VoteCast completed over 47,000 interviews with registered voters across 17 states covering six different election days. Data collection began six days before each primary and ran through poll close in each state. VoteCast was conducted in: Iowa, New Hampshire, South Carolina, Alabama, California, Colorado, Minnesota, Massachusetts, North Carolina, Texas, Virginia, Michigan, Missouri, Mississippi, Arizona, Florida, and Illinois.
In the 2020 general election, VoteCast completed more than 130,000 interviews with registered voters between October 26 and November 3, concluding as polls closed on Election Day. AP VoteCast delivered data about the presidential election in all 50 states, as well as all Senate and governors’ races in 2020.
Not only did the 2020 surveys complete a massive number of interviews with voters and nonvoters in a short turnaround, their results were comprehensive and accurate when compared with key benchmarks. Because of their confidence in the data, both The Associated Press and Fox News used the data to call race outcomes and to explain the mood of the electorate in their election-night coverage.
AP and NORC are committed to transparency of VoteCast’s methods and results, as well as the continual improvement of the VoteCast methodology over time.
