I concur. IMHO, the Republican/Democrat lines blur as soon as you hit Hwy 5 in Douglasville on Eastbound 20, then you’re looking at straight up Democrat voters by the time you hit South Fulton.
Fulton County, Muscogee County (Columbus), and the counties that are basically any of the 4 largest cities are liberal. Most of the smaller cities and rural counties go conservative with some exceptions. Some counties are majority black so they vote Democrat every time.
