I would safely guess democrats. Just as there are more mainline (moderate/liberal) Christians in total here, than conservative biblical Christians. Regular church attendence is somewhat of a marker, as the conservative members tend to frequent masses/services more than liberals do.
I bet the pol-agents have specific records. They seem to have whatever data they need to target demographics.
My parents are South Omaha Democrats and they’ll moan and wail about abortion but still pull the lever. As a conservative I have issues with the Republican party but none of them are fundamentally foundational or value based like abortion. I even have an aunt that is a nun that loves Obama. I just don’t get it.
