The Louisiana Secretary of State has a voter portal in which once can find the party affiliation of any voter living in the state: living people only, not deceased ones. One must also need the zip code or the month and year of birth. Check out some of the Baptist pastors you know and see about their voting affiliation. I also seem to recall that for years Billy Graham was a NC Democrat, but he may not be now.
I already have the Southern Baptist data, for instance in 2008 80% of SB pastors were committed to voting republican, 4% were going third party, and 15% were not sure how they were going to vote.
I called that ‘least 80% of them voting republican’ they appear to be every bit as republican voting as the Southern Baptist members, who also vote at least 80% republican.
Many Southerners are registered Democrats but vote Republican. They will even tell you they are Democrats even though they do not vote as Democrats and share none of the Party’s ideas. The reason is family. Their daddy and their grandaddies were Democrats going back generations so they remain Democrats, although often in name only.
Remember Republicans were reviled in the South from at least Lincoln onward and Roosevelt was seen as the savior of the Great Depression.
My own grandmother would say she was a proud Democrat and when asked why would launch into near worship for Roosevelt. Nothing could change her mind. He hung the moon for her and many of my grandparents’ and my parents’ generations.
