I can only assume you don’t know much about GA politics. That’s the GA 6th Congressional District, Newt’s old stomping grounds from the era when he was Speaker. It’s still generally conservative.
I used to spend 3 to 5 days per week in Atlanta but I changed careers in 95. I still have a lot of friends in Marietta that I maintain contact with me. They all say Marietta has changed a lot since then. If they are wrong so be it. I live in Jefferson County AL which is pretty conservative. But Birmingham, the largest city in the county, (but shrinking in population), is blue as blue can be.
