NONE! They have presented ZERO evidence that anybody is prevented from getting government issued photo ID in NC.
Photo ID requirements deter wanted criminals from voting. All photo ID photos are entered into a database that can be searched for duplicates with fake ID's. They can be matched up to outstanding warrants. A few years ago I was an Alternate Judge on election day, and there was a guy who presented a driver's license that was so far out of date (more than 4 years old), that we couldn't allow him to vote. The reason he had an out of date driver's license was that the State of Texas had a warrant for his arrest for nonpayment of child support. The Election Judge allowed him to cast a provisional ballot, but that meant he had to go to the county courthouse with a valid photo ID within a week of election day. I doubt he did that.

I know several homeless people in NC. They all have IDs.
