So what? I have met White Pentecostals that don't really like the GOP either.
Me too. One thing I've observed is that there's a strong connection between political liberalism and sexual libertinism. No matter how much a girl goes to church, thumps the Bible, speaks in tongues, prophesies, dances "in the Spirit", etc, if she votes liberal she's almost invariably sexually corrupt too. (Sometimes I learned this firsthand: several such "good Christian" women tried to seduce me after a few dates.)
So if you're ever tempted to wonder how such seemingly good Christians who've got everything else right, could possibly get the political thing so egregiously wrong, the first place to look is at their sex lives.
Memo to guys who are still single: Never date a liberal. Never. No matter what else she appears to have going for her.
