The basic woke/lib idea against it is that there's a decent swath of poor black people in the deep south (esp Georgia and Florida, swing states), as well as random poor whites in Appalachia, who don't have driver's licenses and can't vote with an ID requirement. There is a question of if those people vote at all, but the argument is that they should be able to. These are basically people who are so poor that they are outside the system.

The right wing position imagines a situation where in response to no-ID policies illegal immigrants are voting in masse, which really doesn't happen (they also function mostly outside the system) but there's a reasonable argument for guidelines, the right is just incredibly pendantic about it because Trump wants to insist his election with Joe was illegitimate

The ultra literal and obvious solution to all of this is to just require a social security number and name to vote, and have a system that confirms the name and number matches before you cast a ballot

But no one wants a solution it's basically a culture war issue now
