Only 48% of Atheists Voted in 2024

Turnout among atheists dropped from 57% in 2020 to 48% in 2024. How could atheists drop the ball like this?

"Among self-identified Christians, 56% voted, which was barely higher than the involvement among people aligned with non-Christian faiths (53%), but significantly higher than among voting-age Americans who have no religious faith (48%)."
