HOLLYWOOD, Fla. — Donald Trump's chief lieutenants told skeptical Republican leaders that the party front-runner has been "projecting an image" so far in the 2016 primary season and "the part that he's been playing is now evolving" in a way that will improve his standing among general election voters.
The message, delivered Thursday behind closed doors in a private briefing, is part of the campaign's intensifying effort to convince party leaders that Trump will moderate his tone in the coming months to help deliver big electoral gains this fall, despite his contentious ways.

Even as his team pressed Trump's case, he raised fresh concern among some conservatives by speaking against North Carolina's "bathroom law," which directs transgender people to use the bathroom that matches the sex on their birth certificates. Trump also came out against the federal government's plan to replace President Andrew Jackson with the civil-rights figure Harriet Tubman on the $20 bill.
The developments came as the Republicans' messy fight for the White House spilled into a seaside resort in south Florida. While candidates in both parties fanned out across the country before important primary contests in the Northeast, Hollywood's Diplomat Resort & Spa was transformed into a palm-treed political battleground.
Trump's newly hired senior aide, Paul Manafort, made the case to Republican National Committee members that Trump has two personalities: one in private and one onstage.
"You'll start to see more depth of the person, the real person. You'll see a real different guy."
"When he's out on the stage, when he's talking about the kinds of things he's talking about on the stump, he's projecting an image that's for that purpose," Manafort said in a private briefing.
"You'll start to see more depth of the person, the real person. You'll see a real different guy," he said.
The Associated Press obtained a recording of the closed-door exchange.
"He gets it," Manafort said of Trump's need to moderate his personality. "The part that he's been playing is evolving into the part that now you've been expecting, but he wasn't ready for, because he had first to complete the first phase. The negatives will come down. The image is going to change."
Carson on Trump: 'He's trying to moderate'
The message was welcomed by some party officials but criticized by others who suggested it raised doubts about his authenticity.
"He's trying to moderate. He's getting better," said Ben Carson, a Trump ally who was part of the Republican's front-runner's RNC outreach team.
While Trump's top advisers were promising Republican leaders that the party front-runner would moderate his message, the candidate was telling voters he wasn't ready to act presidential.
"I just don't know if I want to do it yet," Trump said during a raucous rally in Harrisburg, Pennsylvania, Thursday that was frequently interrupted by protesters.
"At some point, I'm going to be so presidential that you people will be so bored," he said, predicting that the size of his crowds would dwindle if he dialed back his rhetoric.
Drama among Democrats, too
There was evidence of drama on the Democratic side as well.
Prominent Southern Democrats urged Bernie Sanders to stop dismissing Hillary Clinton's landslide primary wins across the South, where the front-runner's popularity among non-whites has helped fuel her success.
Sanders said the results in the South "distort reality" because they came from the country's "most conservative region."
Don Fowler of South Carolina, a former chairman of the Democratic National Committee, and other Clinton supporters told Sanders in a letter that "our national Democratic leaders" should "invest in our races and causes — to amplify our voices, not diminish them."
Trump is increasingly optimistic about his chances in five states holding primary contests Tuesday: Rhode Island, Connecticut, Pennsylvania, Delaware and Maryland. He is now the only Republican candidate who can possibly collect the 1,237-delegate majority needed to claim the nomination before the party's July convention.
Chief rival Ted Cruz hopes Trump will fall short of a nomination-clinching delegate majority so that he can turn enough delegates to his side at the convention to give him the prize.ALSO ON HUFFPOST:
