Catholics, when polled in the USA, lump together the professing and attending, and all the rest who are, at best, what I call Chreaster Catholics, those who only attend on Christmas and Easter, or those who do not attend at all.
However, Protestants are never lumped in together, which would VASTLY alter the political vote %. All the mainline, LGBT supporting-churches together with the Evangelical church goers would drastically skew the percentages.
Note this more focused poll, which includes protestants and catholics who regularly attend services once a week, as well as those who do not:
I think the ONLY people who regularly/weekly go to Christian services but still vote democrat are Blacks.
Yes, but things may be changing. The Dems are voicing their supports of Spanish speakers to the exclusion of Blacks. Trump is also a positive in bringing Black out of Dem Slavery.
Who, knows maybe along with the Wall, Trump will build an Underground Railroad allowing the Negroes to escape the Dem slavery
