“If the purges [of potential voters], challenges and ballot rejections were random, it wouldn’t matter. It’s anything but random. For example, an audit by the State of Washington found that a Black voter was 400% more likely than a white voter to have their mail-in ballot rejected. Rejection of Black in-person votes, according to a US Civil Rights Commission study in Florida, ran 14.3% or one in seven ballots cast.”
"[…] Democracy can win* despite the 2.3% suppression headwind.
And that’s our job as Americans: to end the purges, the vigilante challenges, the ballot rejections and the attitude that this is all somehow OK."
The biggest and most obvious is that ID isn’t available to literally everyone who can legally vote without cost to the end user of any kind, and as a consequence requiring such an ID is tantamount to a poll tax. Federal ID that’s fully subsidized would be the easiest solution, and if done right you could even optionally fold most state ID systems into a federal one with things like being licensed to drive being an endorsement on the federal ID.
Notably, the same people who demand photo ID to vote also tend to be the people terrified of a federal ID as a concept.
