VoteCast debuted for the 2018 midterm elections after years of testing and development and was used again for the 2020 Democratic primaries, 2020 presidential election, 2020 special Senate elections in Georgia, 2021 gubernatorial election in Virginia, and 2022 midterm elections. Using a random, probability-based sample of registered voters to carefully calibrate a very large sample from opt-in, online panels, VoteCast delivered the best of both methods – the accuracy of probability-based surveys combined with the scale provided by an opt-in survey that interviews tens of thousands of people quickly. It provided results in every state holding a statewide election, which meant VoteCast delivered a broader portrait of the American electorate than any other election survey.
