Today’s Doonesbury strip gets it wrong, as is pretty usual. The Georgia law does not require anything more of any one group than of another. It simply says that you must show some form of proof that you are who you say you are – that is, an ID card, like a driver’s license – before you can vote. The state has even offered to make it easy and free to acquire an ID card, if an applicant can’t afford one. This kind of ID is a necessity for nearly all adults – the only exceptions are the non-driving elderly, the most extreme mentally ill or mentally disabled, and people who are independently wealthy and don’t work. Anyone else without one of these forms of ID is probably not holding down a job or doing anything productive; for the rare exceptions (say, poor commuters using mass transit) who just can’t afford an ID, it’s free to get one. This is not an unduly burdensome law, nor does it single out any group or groups for special treatment.
You can read Georgia’s current law on the subject (well, the Secretary of State’s summary of it) here.
