If the Dems play identity politics and minorities vote lockstep with the Dems, why shouldn’t the GOP appeal to white voters who have voted majority Rep for several decades.
The GOP doesn’t.
The GOP doesn’t like it’s base at all.
An interesting academic point. The trouble is at this point is is simply academic Trump’s politics have nothing to do with skin color. Their almost entirely about economics.
Trump simply wants to practice the same immigration policy Mexico and most other countries of the world practices, and the United States too uses to practice. Its called respect our laws and wait your turn or get kicked out.
