Southern black voters for Biden
Any evidence for that?
Go to a black church in the south. The 40+ crowd does not tolerate LGBT at all.
I once saw a black preacher talk about voting Democrat to protect food stamps and Medicaid. The same preacher also said those who got abortions were going to hell and the crowd nodded their heads (black, mostly older than 50).
I don't doubt that there are such Southern blacks who vote Democratic, but Alabama's rural black counties ran far behind comparable white ones on banning same-sex marriage in 2006. When the abortion ban was on the ballot a few years ago they were 70% against to the state's 60% for. And that's ignoring the white minority vote.
Southern black voters as a whole are not right-wing conservatives who happen to vote for the Democrats.
