that was literally it. White Identity politics. The SCOTUS has long been the GOP unicorn to activist-judge themselves into sending this country back two thousand years of progress and pure white hegemony, and that was all Trump ever was to the people that held their noses for him. Trump gave them that, 90+ federal seats unethically blocked by Mitch the Bitch during 8 years of Obama gave them more of that.
GOP voters don't have a thinking brain. They have an emotional one. This is literally all it will take.
