A buoyant President Trump on Friday made a campaign-style speech at a Boeing plant in South Carolina — basking in the crowd’s cheers and soaking up some love from the state’s star-struck governor.

“This may be the single greatest day in the history of South Carolina!” gushed Gov. Henry McMaster.

And Trump was equally magnanimous in his praise of ­McMaster — once again boasting about his election victory during the lovefest.

“I have to say, I love South Carolina. Remember we came down all together, and this was going to be a place that was tough to win and we won in a landslide,” he said.

Trump won the state with 55 percent of the vote to Hillary Clinton’s 41 percent.

“So I want to thank the people of South Carolina and your governor — tremendous guy. He supported us right from the ­beginning.”

The stop was intended to showcase Boeing’s new 787-10 Dreamliner passenger jet, with the president declaring, “That is one beautiful airplane. Congratulations to the men and women here who built it.”

But the event quickly turned into a rally reminiscent of his raucous campaign as he talked about job creation, increasing energy production and putting America first.

“From now on it’s going to be America first. Working together as a unit, there is nothing we cannot accomplish,” he said.

The president repeated his vow to get American companies to create more jobs in the US instead of shipping them overseas.

And a day after airing his grievances at the press, his critics and government leaks, Trump seemed happy to be back in front of a cheering crowd, even cracking a few jokes.

“I used to get paid to make these speeches” before he ­became president, he quipped.

One analyst said the campaign-style events seem to energize Trump, who has a rally planned in Florida on Saturday.

“If the White House inner circle wants to keep the boss happy, they should schedule a rally six days a week, with golf all day on Sunday. Trump seems at his most ebullient in these activities,” Larry Sabato, director of the University of Virginia’s Center for Politics, told The Post.

Hours after the event, Trump again attacked the media on Twitter.

“The FAKE NEWS media (failing @nytimes, @NBCNews, @ABC, @CBS, @CNN) is not my enemy, it is the enemy of the American People!” he tweeted.
