They may be able to register without a photo ID, but do those states allow them to VOTE without an photo ID?
What does it matter at that point? They can simply stuff the ballot with said voters and match it against that registrant; photo ID or not.
Texas requires a government photo ID, but lawsuits have weakened that to allow a “provisional” ballot with an approved photo ID submitted soon after. But you can bet that these ballots are counted regardless. Otherwise,.... “racist!!”
