I see. So if a trend doesn’t conform to your prejudice (Catholic voting rather than Southern voting), it is a simple aberation that will switch back, and if it flat contradicts your general theory (black Protestants) you throw it away as inapplicable.
“Lies, damn lies, and statstics,” indeed!
The Southern vote includes Catholics as well, and blacks are always included as part of the Protestant voting numbers.
Did you get that, the 92% Democrat black Protestant vote is always included in Protestant totals.
