State ID (usually a driver’s license) is the defacto universal ID system.
It’s not hard to get, and you need it to do everything from filling a scheduled prescription, buying alcohol, entering a bar, flying on a plane, or purchasing cold medicine. You literally cannot function as an independent adult without one.
You also need to show it — along with a second form of ID — to be hired at a job.
Anyone claiming a state ID requirement meaningfully prevents anyone from voting is being deeply unserious.
If they actually believed what they claim, they’d be campaigning to remove the ID requirements that are already pervasive in our daily lives. They are not.
I’ll also note that buying a gun requires not just multiple forms of ID, but also an entire background check. If we can do that for one constitutionally enumerated right, we can damn well require a photo ID to cast a ballot.
