There are moments in a campaign that are defining. Typically unplanned and unscripted, they reveal a candidate’s true personality and priorities in a moment of clarity that the best political operative cannot spin or explain away.

Such a moment occurred in Donald Trump’s campaign recently in Turnberry, Scotland.

Candidate Trump began the week on a high note. On the prior Wednesday, he had read a speech from a teleprompter that was a scathing attack on his opponent, Hillary Clinton. Giving credit where credit is due, he did a workmanlike job mouthing, with appropriate outrage, a script obviously assembled by a professional. It trotted out about every canard ever aimed at the presumptive Democrat nominee in the last 25 years, and wove them all together in a narrative of conspiracy theory upon conspiracy theory so titillating that Hillary, had she listened to the speech, probably wouldn’t vote for Hillary either.

Of course, just because the charge is made does not make the charge true, no matter how often it is repeated. According to Politifacts, a Pulitizer Prize-winning fact-checking service, 77 percent of what came out of The Donald’s mouth ranged from “mostly false” to “pants on fire” fabrication. If, as Mr. Trump claims, Hillary Clinton if the greatest liar in the world, it is only because he is too self-deprecating to claim the title for himself.

On June 23, the Kingdom formerly described as “United” voted to withdraw from the European Union, the so-called “Brexit.” This doesn’t mean much to Americans since we are exceptional, and somehow insulated from the nasty globalized world around us, but it was a really, really big deal to the rest of the unexceptional world.

The next morning, The Donald convened a meeting of the world’s political press to show off his newly reopened (and gorgeous) Trump Turnberry, a Luxury Collection Resort, on the southwest coast of Scotland (beautiful country, friendly people, don’t go for the weather).

By the end of the day, because of the Brexit vote, the New York Stock Exchange would fall over 600 points. Two trillion dollars of paper value would be wiped out worldwide, and the average 401K plan in the United States, assuming you were lucky enough to have one, would lose something over $3,100 in value.   The British pound sterling would close at its lowest level since the glory years of Maggie Thatcher back in 1985 (or the gory years depending on your political persuasion).

To be fair, the full extent of the carnage was unknown as The Donald extolled the virtues of Turnberry’ new in-ground sprinkler system to the world’s press, but it was obvious early that Brexit was causing a world-wide financial upheaval that the original boys from Ghostbusters would describe as being of biblical proportions.

Finally, after extolling the magnificence of the luxury suites in the former lighthouse keeper’s quarters, Donald Trump, presumptive nominee of the Republican Party for the Office of President of the United States and de facto leader of the free world, was cornered into offering a few words on the rapidly developing financial crisis.

First of all, he congratulated the Kingdom formerly described as “United” on the outcome of the vote, noting that they had taken their country back much as Americans will when he is elected president.

As to the crumbling value of the local currency, The Donald opined that the less valuable the pound sterling became, the more folks would be flocking to Trump Turnberry, a Luxury Collection Resort.

There are moments in a campaign that are defining. Typically unplanned and unscripted, they reveal a candidate’s true personality and priorities in a moment of clarity that the best political operative cannot spin or explain away.

When faced with a global financial crisis, Donald Trump’s first thought was how it would affect him, and his personal bottom line. The fact a pound sterling rapidly losing value would significantly reduce buying power and make it even harder for Britons to make ends meet didn’t appear to register. It was all about him.

To make matters worse, Mr. Trump’s comments were made in Scotland, one of the sovereign kingdoms within the Kingdom formerly described as “United,” whose citizens voted 62-38 percent to stay inside the European Union. They didn’t want to take their country anywhere.

He was very lucky a disgruntled grounds keeper didn’t sic an angry wee wild haggis on him.

I doubt if any of this means much to Trump loyalists. But it should.

He might not be so much for you as he is for himself.
