This is that garbage Pew report from
… 8,942 U.S. citizens ages 18 and older who are members of the Center’s American Trends Panel (ATP). We verified their turnout in the five general elections from 2016 to 2024 using commercial voter files that collect publicly available official state turnout records.
It’s bullshit and the reason why is right there - and the fact that they ran the survey two weeks after the election. Idiocy.
