"With his Super Tuesday wins, the tycoon fuels a bloody civil war. .... he threatens not only to smash up the GOP but to blow apart the conservative movement. The conflicts he has detonated will not easily be resolved. He presents an irreconcilable difference. ... However the GOPers and conservatives handle this existential challenge, it likely won't be pretty or classy."
