The emperor has no clothes.

Whatever happens Tuesday, and I’m not that optimistic, at least Donald Trump’s campaign has exposed the utter moral and ethical bankruptcy of the American establishment from top to bottom.

They’re frauds — the Democrats, their media coatholders, the Paul Ryan Republicans, Wall Street, all of them. And they are so, so unhappy — they don’t just hate the “deplorables,” the “irredeemables” and the “bitter clingers.” They despise one another. They hate themselves.

From WikiLeaks, we know the disdain they have for “medieval” Catholics and “needy Latinos.”

We’ve long understood the Clintons’ breathtaking contempt for “the help” — Secret Service agents, the military, basically anyone in uniform. Now we’re discovering the Clintons’ supposed acolytes feel the same way about their masters. They say no man is a hero to his valet, and to the Clintons, we are all valets.

Doug Band writes a withering email to Podesta saying Chelsea is “not smart.”

Podesta replies: “You’re perfecting your skills for understatement.”

Neera Tunden exhorts Podesta to stay on Hillary’s case and “eventually (she) will sound like a human.”

I doubt it, Neera.

As Dave Chappelle, the comedian, told an audience in New York Friday night, “She’s not right and we all know it.”

She and all the people who surround her.

They’re these inside-the-Beltway, trust-funded supercilious snots from third-tier Ivy League wannabe schools who, as Victor Davis Hanson put it, “sound quite clever without being especially bright, attuned to social justice without character. Their religion is not so much progressivism as appearing cool and hip and ‘right’ on the issues … . Well-connected and mediocre … . They write and sound off about the buffoon Trump and preen in sanctimonious moral outrage … .”

Even if Hillary staggers across the finish line Tuesday, does anyone really think she can put the genie back in the bottle? Half the country is checking out, has checked out already. Nobody reads the Hillary-worshipping newspapers anymore, or watches their crappy TV networks. They have not a shred of moral authority.

I’m not worried so much right now about the Second Amendment — Robby Mook and George Stephanopoulos and the rest of the pajama boys won’t be kicking down anyone’s doors anytime soon, although higher taxes on ammo are certainly on the agenda. Via executive order, of course. Why go the constitutional route when Hillary’s new and improved Supreme Court will rubber-stamp everything?

Banana Republic — it’s not just an overpriced clothing store in the mall anymore. We’re living in one, have been for eight years now.

If Hillary wins, it’s going to be a long winter for the Little Sisters of the Poor and independent filmmakers and anyone else who relies on the protections of the First Amendment. As for the rest of us, these next few years are going to be a lot like they were for dejected Roman citizens in the fifth century A.D.

The Empire’s over, the barbarian hordes have breached the gates, but if you can just get a flat-bottomed boat and flee to those swamps around Venice, maybe you can fortify the Grand Canal and hold out against the Goths a little while longer.

As has become abundantly clear, the Clintons don’t believe they are bound by any laws that inconvenience them in the slightest. After all, she’s on record in Brazil as saying that her dream is “open borders.” Which are, of course, against the law. But like Obama, Hillary wants to import a replacement population, one as amoral and shiftless as she and her followers. People who, you might say, don’t need no stinkin’ badges.

If you believe that we are a nation of laws, not men, if you want the laws enforced, especially “without fear or favor” as they used to say — then Hillary and her supporters denounce you as a, uh, racist, or something.

John Adams once wrote of the new republic: “Our constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.”

Are we still a moral and religious people? Sadly, I think we all know the answer to that question — even before the polls open Tuesday.
