Maybe, but he’ll bring in the black vote. And libs will be too afraid to attack him because... racism.
NO HE WON”T!
Blacks who are going to vote for Trump will do so regardless of who he picks and may see a black running mate as pandering. Furthermore, a black running mate will undoubtedly cost him some white votes. Maybe not many, but definitely some. Perhaps enough to lose North Carolina and Georgia.
Anyways, I don't know why the conventional wisdom is that we have to try so hard to get black votes.
Latinos are where the money is. They've been largely abandoned by the Democrats and they're the biggest minority voting block out there (even if multi-ethnic Latinos don't vote as a monolithic block).
You didn’t notice that they attack black conservatives all the time?
