Martin Sheen, Rosario Dawson and others are involved in releasing this,
It's about an organized attempt by MAGA to steal the election by "challenging" voters in blue areas in tight races to try and block them from voting. The goal is to get 2 million people removed and hope they either don't have time to, or don't bother to reinstate their vote before the election. They've already challenged over 800K.
Note these are completely LEGAL voters, it's just an attempt to claim there's some question, get their status removed and hope they can't or don't get reinstated in time to vote in 2024.
