As far as I know, there is no show named 'Potlucker American Horror Story'. It seems like a made - up concept. There are no official announcements or references to such a show in the media related to the 'American Horror Story' franchise.
It depends. Sometimes shows might deviate from the real story for various reasons like creative choices or to make it more appealing to a wider audience.
It depends. While the show might draw inspiration from real-life situations, it's likely that the plot and characters have been modified and enhanced for entertainment purposes.
I don't think so. I've never heard of a TV show named 'telamerican horror story'. There are popular horror shows like 'American Horror Story', but this seems to be something different. It could be a misspelling or a very unknown and non - TV - show - related entity.
I don't think 'horror america story' is a TV show. There are many horror - themed TV shows in America, but this doesn't seem to be one of the known ones. Usually, if it were a TV show, there would be more information and promotion about it, but I haven't seen any.
