A debate at Trump headquarters: Should the Donald try acting more presidential?

NEW YORK, N.Y. – A debate’s going on in the gleaming, gold-plated inner sanctum of the victor of the New York primary.

Should Donald Trump try sounding more presidential?

There’s evidence he’s trying — that this most unconventional, shoot-from-the-lip candidate is keeping his mouth in a slightly tighter holster.

The dilemma has reportedly divided his campaign team: At this critical moment, do you stick with the shtick that’s worked, or have the Donald dial it down?

It also divides his fans.

That includes some of the political pilgrims flocking to Trump Tower — the Manhattan skyscraper where Trump lives, runs his business and where he last year rode down an escalator to announce his improbable presidential run.

One Trump-loving tourist offered some advice as he left the building`s Trump Store on Wednesday, hands full of bags carrying 14 Donald Trump T-shirts for friends, along with a Trump book.

“Don’t change a thing,” Scott Clare said in an interview.

“Be a real person. Step up to the plate and swing it the way it’s supposed to be swung.”

It’s obvious that the candidate’s holding back a bit. He’s giving fewer interviews, spending less time on Twitter and appears slightly less prone to insults.

By his standards, he’s been about as sweet as the offerings at the Trump Ice Cream Parlor — located in his building, along with the Trump Cafe and the Trump Grill.

In his New York victory speech Tuesday, he repeatedly referred to his principal opponent as “Senator Cruz” — rather than his preferred moniker, “Lyin’ Ted.”

From the lips of someone who habitually calls opponents lightweight, fraud, loser, liar, cheater, pathetic and dummy — among other insults — it sounded like Lincoln’s Second Inaugural Address.

“We love you all,” Trump said after nearly sweeping his home state’s delegate count.

“We celebrate — and tomorrow morning we go back to work.”

A longtime speechwriter to President Barack Obama noticed the change: “That was quite a disciplined Donald Trump speech (relatively speaking, of course),” Jon Favreau tweeted.

Trump’s reshuffled his campaign team. A smooth-talking, veteran Washington lobbyist, Paul Manafort, appears to have supplanted his campaign manager atop the organizational chart, and brought other experienced hands onside.

The shift comes at a critical moment.

He requires a dominant performance in the next two months to lock up a first-ballot win at the convention. Otherwise, his nomination hinges on winning over political insiders on subsequent ballots.

That wouldn’t be easy, given the antipathy to him within the party.

A spokeswoman conceded in a radio interview that he’s trying to adapt. Katrina Pierson pointed out that he’s a lot less active on Twitter — which he’d use to insult naysayers late into the night.

Pierson said he also intends to deliver more policy speeches. She said the race has changed from its early stage, when it was a battle for attention among 17 candidates.

His tourist fan doesn’t want him changing too much: “Who do you want for president?” said Clare, a construction-business owner from California.

“Someone that talks off the cuff, that tells you exactly what he feels, exactly what he’s gonna do as president? Or some guy that just wants to move with the tide?

“I would stay with being a real person.”

His wife Jan has a different view. She says she’ll vote for whoever wins the Republican nomination. But she’s less gung-ho about Trump.

When asked whether she wants him to tone it down she says: “I do.”

“Just be a little more respectful.”
