Hope? Yes, absolutely. But this cultural norm has been very durable.
Still, the best evidence that there could be something to this theory is that Leftist Black intellectuals are now worried about the possibility. I don’t know if they are responding to the same anecdata (anecdotes masquerading as data) or whether they have a legitimate reason to be worried about a surge of support for Republicans by Black voters.
… Republicans don’t want to “own” the Black vote. We want to earn it. Democrats are scared to death that we will if we can get a hearing.
BUT, will Republicans ever get a hearing? Not if the Left can prevent it!
