“”””I’ll have these n*ggers voting demonRAT for the next 200 years”, and he was right.”””

That quote puzzles me because the black vote permanently reversed in 1936.

Only in the North. Southern Blacks (those that could vote) didn’t fully go to the dark side until 1964.

Here is an explanation and some charts illustrating your point. Although the reversal began with FDR, it wasn't "complete" -- both party identification and actual voting preference -- until Truman.

I notice that the source article from FactCheck is from 2008, so it leaves out the years that would have shown a surge in blacks voting GOP for Trump.
