It's actually kind of strange, because Glascock is surrounded by several majority black counties in the Georgia black belt, yet it's well over 80% white
Beat me to it. There's actually a lot of reported racial tension here as you're right; Glascock County is a 90% white county surrounded by majority black counties. The political tension here is also evident when you look next door to Hancock County, which was the second most Democratic county in Georgia in 2008. In 2004, Hancock County was the most Democratic county while Glascock was the second most Republican. Similar results can be seen between the two counties in 2000 as well.
