Who was it originally sent to? Strikes me as something which would be sent to white voters in the SEC states to try to nudge racists to vote against Trump. I’d look and see which of the other campaigns was behind it.
A modern version of getting a pregnant black lady to sit on the front row at a rally. Don’t think I’ve heard of that being used for at least 30 or 40 years.
Your “THEORY” is all wet. Allen West was defeated in the Florida Rep. reelection by the Blacks who voted en bloc for the Democrat. West was supported by the Whites. Me among them.
