Christian nationalist ideology was a robust predictor of voting for Trump in 2016.

They specifically called out in the description "we did not measure those who did not vote for Donald Trump."

They did survey democrats. They even stratified to make sure they good a representative cross section

So no... They did not. They did not do a cross culture isolation comparison of Christians of Trump VS Hillary. All three professors also assumed racist, sexist, or Islamophobia(sp?) was the root cause if Christian slant for Trump, rather than against Hillary. Form factor analysis of the r square provided shows less than 0.004 result showing a meager correlation between the questions about Nationalistic Christianity and Trump.

In layman's terms, they tailored the questions to a specific audience and marveled when the audience reacted to specific crafted questions about nationalistic Christianity rather than use Kant's paradigm, Sylvester's axiom, or even a standard double blind.

I also love how they didn't ask anyone how often they go to church in the questions either, but if they just profess Christian ideology. That should be a HUGE give away that this was a faux study.
