This is an easy question. The political right wing of this country has segregated itself to contain mostly white people.
While there are a few minorities involved with the right wing, for the most part, the right wing of this country wants to keep itself a "white entity".
The montra of bring back "our" america is nothing more than a dog whistle for "bring back white controlled america".
This is why the right wing of this country will continue to lose elections on a national level.
The days of the old white guys running the country have run out of time.
Its easy to keep old white people in line with political rhetoric and distortions, as all anyone has to do is listen to the morelucks, and islands and oldgrays, and Av8's of the board for the days talking points.
Its all about selling hate.
The right wing has masterfully sold hate to convey a message that somehow translates into something people can really buy into, (if your white that is)
They call it truth, but the country knows, its B.S.
TOS.
