Donald Trump is tearing the Republican Party apart. He’s not just doing so because he rejects both basic decency and traditional conservatism. He’s doing so because he’s spurred war between his followers and other conservatives.
On the one side, there are Trump supporters who claim that non-nationalist populist conservatives paint them with too broad a brush. That’s not unfair. There are many reasons people support Trump, some mediocre (he fights!), some downright gross (he’ll stand up for white people!).
