This assumes that in, say, 2035, we will consider the same people to be "minorities" as now. That's a big assumption. In the past, groups "became" white. I don't see why this is not going to happen now.
True. Once miscegenation becomes even further mainstream, this country will be 95-100% white again. The GOP will be in good shape once that happens, but it may be a while.
miscegenation? do you mean interracial marriage?
I'm a Republican and of the 8 women I've dated in my life, less than half were white. 3 black, 1 middle eastern, 1 Asian.
Republicans aren't racist, unlike Ron Paul "libertarians" or whatever
