I wouldn't be surprised if Episcopalians are a bit more Republican than you all think--probably still Democratic, at least since 2016, but they still are very much an elite white conservative church in the South.
There's also the question of how devout someone needs to be to be considered a member of a certain religion. For example, I would imagine that people who attend Episcopalian services every Sunday are still a good bit to the right of the overall population that would check 'Episcopalian' on a form. Also, are we counting more conservative Anglican congregations as Episcopalian here?
