Detailed tables for "Behind Biden's 2020 Victory"
Note (July 2023): A new report about the 2022 validated voters used slightly revised 2020 estimates. There was nothing inaccurate about the 2020 results, but we chose to use a slightly different survey weighting approach that increases the precision of our estimates. None of the substantive findings have been impacted. To view the revised 2020 data, click here. See the 2022 methodology for more detail.
