I live in Georgia, and I do not recall the source, but I read that one needs to be registered to vote in Georgia by December 7th.
To Brian Kemp's credit, when he was Sec of State in Georgia, he purged the voter roles in Georgia. People that did not vote in seven years, and did not respond to multiple requests for them to verify they are still a resident and voter in Georgia, he purged them from the voter rolls. That is what Stacey Abrams with her single brain cell has been crying about for nearly two years, that Kemp cheated her out of the election. I guess she was relying on the dead, and those that moved away to vote for her. She is an idiot, and should not hold any position above dog catcher.
