BALMEDIE, Scotland — On the 10th hole of his golf resort here, Donald J. Trump — asked if defeating Hillary Clinton in November was more of “a par-3 or a par-5” — said it would “be very easy.” And on the 18th, when asked if he had more or fewer candidates on his vice-presidential short list than the par of the hole (a five), Mr. Trump allowed, “I’m getting calls from a lot of people, and they want it.”

Such was Mr. Trump’s whirlwind afternoon at Trump International Golf Links here: He touched down on Saturday in his helicopter and, a day after Britain’s vote to leave the European Union threw global markets into chaos, led the international news media on a mad scramble through the dunes of his windswept golf course.

Mr. Trump was finishing a two-day publicity tour of his Scotland golf resorts — on Friday, he visited Trump Turnberry — but between ribbon cuttings and family photos, news of Britain’s referendum kept intruding.

Asked what he would tell voters back home who are worried about losing their retirement savings, Mr. Trump dismissed the question. “Americans are very much different,” he said. “This shouldn’t even affect them. I mean frankly, if it’s done properly, if we had proper leadership.”
