Muslims being way more D than Hindus as late as 2020 is surprising to me.
Man, people really want to believe that Muslims are going to start voting Republican any day now even in the absence of any evidence.
I think a nontrivial factor in Trump winning Orthodox Christians by landslide margins is Middle Eastern Christians resonating with GOP suspicion of Islam.
The Orthodox number was curious to me, because when I think of Orthodox Americans I think of Greeks, who might vote Republican on aggregate but certainly don't seem like an overwhelmingly Republican demographic (most of the Greek politicians who come to mind are Democrats). Your explanation makes sense in this regard.
