Doesn't the fact that hotbeds of the far left are all attractive vacations spots abd hotbeds of the far right are hellholes everyone wants to avoid tell you something?
As for the question: Forsyth, GA is your answer. I'm glad BRTD was able to point that one out a few years back. Northern GA as a whole seems to be right wing cuckoo land.
I'm not sure you can call Martha's Vineyard a hotbed of far left, perhaps socially but that still cannot count as a far left hotbed in a way you compare to a KKK enclave. If anything the hotbeds of far left will be in NYC\Seattle\Boston\Large cities with old Socialist-Intelligentsia
