This report utilizes survey data to better understand the viewpoints of Americans who believe the 2020 presidential election was stolen. The September and November 2020 VOTER Surveys (Views of the Electorate Research Survey) was conducted in partnership with the survey firm YouGov. In total, 5,900 adults (age 18 and up) took the survey online between August 28, 2020 and September 28, 2020. Of those 5,900 respondents, 4,943 were reinterviewed after the election between November 13, 2020 and December 7, 2020. Many of these respondents were long-term panelists originally interviewed by YouGov in 2011-2012 as part of the Cooperative Campaign Analysis Project (CCAP) and then again in the December 2016 VOTER Survey. In total, 3,750 of these long-term panelists participated in the September 2020 wave and 3,340 participated in the November 2020 wave.
