“Do you think any of it sunk in?”
The three blacks I’ve hired, all in their twenties, are died-in-the-wool Democrats. They know no history at all. None. They can tell you who is president now and they recognize the evil Bush. But they don’t know the name Carter or Ford. They are not dumb. But they are not educated and are politically illiterate. They will vote Democrat. It’s rather like chickens voting for Colonel Sanders. So, in answer to your question, no.
Perhaps you could explain why you bothered to even try to educate these people?
