Do you remember what happened when the Berlin Wall fell? Until that moment, nobody realized just how decadent Communism had become. It had tanks, guns, and nukes, but nobody really believed in its ideology anymore; its officials and enforcers were mere careerists, who folded at the first shock.

It seems to me that you need to think about what happened to the G.O.P. this election cycle the same way.

The Republican establishment was easily overthrown because it was already hollow at the core. Donald Trump’s taunts about “low-energy” Jeb Bush and “little Marco” Rubio worked because they contained a large element of truth. When Mr. Bush and Mr. Rubio dutifully repeated the usual conservative clichés, you could see that there was no sense of conviction behind their recitations. All it took was the huffing and puffing of a loud-mouthed showman to blow their houses down.

But as Mr. Trump is finding out, the Democratic establishment is different.

As some political scientists are now acknowledging, America’s two major parties are not at all symmetric. The G.O.P. is, or was until Mr. Trump arrived, a top-down hierarchical structure enforcing a strict, ideologically pure party line. The Democrats, by contrast, are a “coalition of social groups,” from teachers’ unions to Planned Parenthood, seeking specific benefits from government action.
