What's Next for Donald Trump's Campaign? Republican Delegates Sound Off: 'He Needs to Discover Humility'

Donald Trump promised Republicans an entertaining showbiz spectacle at their national convention. But as the confetti is swept up in Cleveland and Trump's presidential race heads toward Election Day, the hiccups of this pivotal week have some Republican delegates wondering if their nominee can get his campaign in order – let alone run the nation.

First, a Trump employee admitted to plagiarizing passages of Melania Trump's convention speech – from Michelle Obama's 2008 convention speech. Two days later, Trump gave a coveted prime-time speaking slot to rival Sen. Ted Cruz – only to have the Texas senator use the platform for pointedly refusing to endorse Trump.

"I think Trump needs to apologize to Ted Cruz after the horrible, goofy and immature comments Trump made about Heidi Cruz's looks and Cruz's father playing a role in John F. Kennedy's assassination," says Jacob Rossi, 19, a Texas delegate and political science major at Texas A&M.

"He needs to discover humility and learn how to apologize, If he does, I believe he has a great chance of winning because he has good social conservative ideas that we need. He can regain credibility."

Rossi feels Trump has helped his campaign by selecting conservative and politically experienced Indiana Gov. Mike Pence as his running mate. But the student says that Trump needs to show more leadership and maturity after the week of mishaps, and a primary season filled with fear and loathing.

"Trump has proposed solutions to immigration and economic problems, illustrated good choices for the Supreme Court and promises economic reform," says Rossi. "But he needs to mend his fences."

Other delegates interviewed by PEOPLE in Cleveland also want to see some proof that Trump, a businessman with no experience in government or elected office, will run an effective campaign.

"It might be helpful if he tones down," says Nicholas Allman, 23, a Texas delegate and Trinity University student.

"Donald Trump is Donald Trump and it is in his nature to talk off the cuff. It has helped him so far but he now has an uphill battle. He has to convince the general public he can run an effective operation."

Some see promise in his mastery of social media and round-the-clock tweeting.

"It has helped him and will continue to help him this fall because it's a medium of conversation that proves Trump understands technology and he gets people to communicate," says Robin Bernstein, a Florida delegate at large and businesswoman in the insurance industry.

"I think he can win convincingly. Never bet against Donald Trump."

Then there's the question of acting more presidential.

Carolyn McLarty, a delegate from northwest Oklahoma, likes that Trump is not entrenched in the political establishment, but is also worried about his outrageous comments and seeming lack of control when under pressure.

"I see how he has begun to surround himself with top-notch people like Pence, but [Trump] still gets a little too far off of the cuff," says McLarty.

"I think he has genuinely good ideas and now has the opportunity to run a solid campaign. I hope he does."

Other delegates like Trump’s outspoken nature and repudiation of established politicians and government. They think he can win by being himself because he is fresh and the opposite of Hillary Clinton, who they see as more of the same – an extension of the Obama administration.

"Trump listens to our needs," says Jan Breitenstine, a Texas delegate. "He knows how to communicate at the grassroots level. He wants to close our borders for safety and help the economy. He has more to offer than Hillary Clinton."

Breitenstine hopes Trump can win but is worried about young and middle-aged women who believe they have to vote for a female even if they don't think Clinton is the best candidate. "I want Trump to tone down so he can win. But, on the other hand, I like that he is politically incorrect," she says. "He just can't be too offending."

Rick Green, a delegate at large who campaigned for Ohio Gov. John Kasich, had initial reservations about Trump and his off-the-cuff remarks yet feels more secure now that Pence is on the ticket.

Green says he's also reassured by Trump's recent campaign staff hires and by the wish list of prospective Supreme Court nominees Trump released earlier this year.

"I trust the judgment of people Trump has on board," says Green, 45, who is chairman of the Massachusetts Fiscal Alliance, a respected political education group.

But moving to Trump from Kasich has been more of a crawl than a sprint for this self-made businessman. "It's a process for me but Trump has my vote."

Another veteran Massachusetts politician, Jim Rappaport, a delegate at large and former state chairman of the Republican Party, agrees that every candidate has to earn the confidence of the electorate.

"Trump hasn't earned mine yet but he is getting warmer with the selection of Pence and his conservative choices for the Supreme Court," says Rapport.

"I have a visceral problem with some of the mocking comments he has made, especially about a reporter with disabilities and John McCain, who is a war hero. Yet I ask myself, how can he be a troglodyte when he has such great children?"

Katrina Campins, a Miami-based contestant on the first season of Trump's reality TV show The Apprentice in 2004, has remained close to him and now sells luxury real estate for one of his companies. Over the years, she has watched him in action and worked with his children.

She has no doubt he will run the country efficiently, treating it like a business and improving the way of life for citizens of all ages.

"People are looking at Trump and feel happy that he has the passion, ability and track record to get the country back in order," says Campins, 36.

"They like that he speaks from the heart. We need that."
