I think beginning and stopping the analysis at the 2016 primaries isn't quite what I was after though. By 2016 a lot of the forces I'm describing have played out insofar as a lot of people have left organized religions and others have decamped for pseudo-religious highly ideological right-wing grifter clubs.
But, anyway, again, just examining Trump voters now:

Pretty sure these are repeatable; I think Pew has a lot of the same style of data.
Obviously these aren't perfect people, we're talking about Trump voters after all, but I think we should weight seriously that participation in social institutions like church makes them less bad.
pwn_master is now joining goofy in "we gotta throw these people a parade??!" but again, not what I'm saying. The point is that as you move people who aren't perfect and float them farther and farther into the "never attends church" column, insofar as we acknowledge that like participating in religious life is a factor (the rub of the argument here I agree), the more you can predict kinda bad people (they are Trump voters after all) are going to turn into HOLLLLY **** WHAT THE ****, OUR COUNTRY?!? kinda people.
