A better bet is that Donald Trump will lead the Republican Party (or what’s left of it) into the abyss. It will be the worst rout since Barry Goldwater lost to Lyndon Johnson in 1964 by 23 percentage points.

I’m assuming Mr. Trump gets the nomination. I can’t see how he won’t. But the electoral math is dreadful. Demographics are not on the GOP’s side. Angry white guys are a shrinking minority of the population. Perhaps half of all Republicans dislike Mr. Trump, and won’t vote for him. Thoughtful people in the party (there are some) believe a Trump nomination will be suicide. The ethical ones will fight him to the bitter end. The opportunistic ones will try to explain why the guy who was a nation-wrecker yesterday is just the man the country needs tomorrow.

Mr. Trump will be opposed by the entire mainstream media except Fox News. Which, come to think of it, might work to his advantage.

Mr. Black actually believes that Mr. Trump can fix the corrupt U.S. government system. In fact, he wants to destroy it, along with what remains of the culture of consensus and compromise. He’s a wrecking ball. He believes experts are idiots and wears his ignorance with pride. He acts on instinct and impulse, makes up stuff as he goes along and scatters his lies like confetti. He’s written more books than he’s read. This does not hurt his ratings. It enhances them.
