Stacy (Tank) Abrams has announced that Georgia currently registers 7.7M voters. This is an impressive number as the census department counts 7.8M adults in the state and this is a raw number which includes everyone with a pulse and respiration.
Somewhat more than that is usually required to legally vote, at least in most states, and no one has bothered to ask what number of those 7.7M voters might be either metabolically or ethereally challenged. Again it varies by state, but most states disenfranchise these sorts of people, at least to some extent.
Not to worry, as I expect that if someone in Georgia is disinclined to go to the trouble of filling out and submitting a ballot, there will be lots of people there who will be pleased to do it for them, and as many times as might seem prudent to insure that the persons preferences are properly expressed.
At this point I would be completely unsurprised to hear, on Jan 6 (or 7th, or 10th or whenever) that Georgia had elected 2 senators with a record setting turnout of 105% or more of the states eligible voting population.
