However, Mr DeSantis’ ability to connect on the campaign trail has been questioned by staff and former staff in an investigation by the Daily Beast website.
He has embraced a “Tallahassee basement strategy, mirroring that of [Joe] Biden in 2020, where he hides from press and real voters”, one Republican strategist said, referring to the capital of Florida, where Mr DeSantis’ office is based.
The Telegraph also spoke to former members of his Tallahassee office about his style.
One associate said: “You will be in the car with Ron and he’ll say nothing to you for an hour. He prefers it that way.”
Those who have worked with him said that he is a natural introvert who has the ability to turn the charisma on when needed.
Observers noted that Mr DeSantis tends to steer clear of the meet-and-greets and avoids the so-called retail politics that Mr Trump excels at.
At a recent Republican Party county event in Texas, supporters paid money to hear Mr DeSantis discuss his latest book, The Courage To Be Free, in a more intimate group.
However, he spent only a few minutes with the pared-down crowd before escaping out a back door, irritating some in attendance.
‘DeSantis is dry compared to Bush’
At other public events, Mr DeSantis has leaned heavily on his wife Casey, a former TV news anchor.
Several former members of the governor’s staff claimed that almost everything he does is scripted.
Francis Rooney, a former congressman and an influential donor in Florida, told Politico: “Ron is a little reserved and dry compared to George W Bush and Bill Clinton. He is what he is. So what he needs to do is organise his campaign to minimise that characteristic.”
One recent report even commented on some of his more bizarre-seeming awkwardness, including the chocolate dessert technique.
“He would sit in meetings and eat in front of people,” a former worker for Mr DeSantis told the Daily Beast. “Always like a starving animal who has never eaten before… getting s— everywhere.”
While Mr Trump has taken aim at his one-time political protegee and now chief rival, calling him “Ron DeSanctimonious” and “Meatball Ron”, Mr DeSantis and his team have failed to respond to the attacks or shift the conversation.
