Americans are such sticklers. Such poops. Sure, some of Vladimir Putin’s political opponents wind up in jail, while some of the journalists he dislikes end up in the morgue. Yes, his government is apparently committing cybercrimes to meddle in our election. And there was that small matter of invading and annexing one of Russia’s neighbors.

But look at his numbers! What’s a little blood on your hands when you’re polling like that?

“He does have an 82 percent approval rating,” Donald Trump said during the special “commander in chief” forum last week. It’s worth dwelling on that sentence, because it’s the key to what drives and guides his presidential bid. It’s the giveaway.

For Trump, the whole point of political office is adulation, and adulation is the entire proof of a person’s worth. Rectitude pales next to ratings. Ethics are a sorry substitute for applause. And the methods by which a crowd is fired up don’t matter, so long as he can bask in the clapping.

This is Trump’s core — or, rather, his terrifying lack of one.

It’s why he swerves from one pronouncement to its opposite and one position to its alternate. It’s why he tells lies with such ease and glee. He’s not sweating the substance of what he’s saying or doing, because that’s a negotiable, trivial thing. He’s just gauging the reaction, and a positive one — in the form of victories in the primaries, dominance in the media or supremacy in polls — means that his course is just. If Trump’s in his heaven, all’s right with the world.
