With this president there’s a surfeit of provocation and a dearth of due diligence.

Where was the vetting, extreme or otherwise, of Mick Mulvaney, the congressman tapped for the Office of Management and Budget? Oops: He had a nanny for whom he’d failed to pay more than $15,000 in taxes.

Where was the vetting, extreme or otherwise, of Steve Mnuchin, just confirmed as Treasury secretary? Oops: He had all this offshore wealth and nearly $100 million worth of real-estate assets that he initially failed to mention in financial disclosure forms.

Where was the vetting — or, more to the point, the preparation — of Betsy DeVos, our new education secretary, who waltzed into her confirmation hearing and theorized that the greatest pedagogical threat to America’s schoolchildren was toothy, furry and fond of salmon.

There have been so many embarrassments with so many nominees that a few who’d be in the foreground of the news otherwise have been spared the derision they deserve.

Andrew Puzder, for instance. He’s up for labor secretary, and his confirmation hearing has been delayed four times as he deals with a tangle of financial interests that are only the half of it.

Puzder runs the fast-food chains Hardee’s and Carl’s Jr. and has spoken dreamily of how much he’d like to install robots in place of human workers — you know, the kind the Labor Department is supposed to protect. In a memo to Hardee’s managers, he once wrote, “No more people behind the counter unless they have all their teeth.”

He’s cuddly, this one. Randy, too. He took great pride in a Carl’s Jr. ad campaign in which models in bikinis wrapped their lips around fleshy, gooey cheeseburgers, giving a whole new meaning to the phrase “food porn.” One ad had a woman whose bare breasts were obscured by melons. Oh, the wit!
