First off, always disbelieve polls, especially when they're telling you what you want to hear. Hillary learned this the hard way.

Second off, this is Trump, not the GOP as a whole.

However, that said, if Trump gets a substantial fraction of the black vote, that's it, gg no re, a shellacking not seen since Reagan. Michigan, Wisconsin, Pennsylvania, Virginia, New Hampshire. The REEEEEEing will be a thing to behold. Some people with the very worst TDS will actually kill themselves over this.
