Donald Trump remains unpopular with some in his own party and the presumptive GOP nominee also faces challenges with younger voters. Among millenials, he has a 75 percent unfavorable rating, reports CBS News correspondent Mo Rocca.
Arizona delegate Amanda Naylor Flores is 18 years old and headed for Harvard in the fall, but remains uncertain for whom she will vote in November.

"It will take a lot for me to vote for Donald Trump in November. I'm Hispanic and young and a female and so it will take a lot for me," Flores said. "I also don't think that Hillary Clinton is a better candidate. And so I don't - I honestly don't know where that leaves us as a country."
At 17, Vermont delegate Jace Laquerre is among the youngest at the convention.
"I was never really a Trump supporter --I probably won't be until he's officially nominated here," Laquerre said.

"What would make you more a less-reluctant Trump voter and a more enthusiastic supporter of his?" Rocca asked.
"Well, I think if he had a more liberty, liberty-oriented message. That's one that resonates with young people you know. Privacy and non-interventionist foreign policy," Laquerre said.
Eighteen-year-old Nevada delegate Ryder Haag is obligated to vote for Trump, according to his state's winner-take-all directive.
"Would you say you have a fire in the belly for Trump?" Rocca asked.
"Yes I do, and that's really more that I represent the people that elected me in and it's not that I loved him at first but I still am going to support him," Haag said.
Haag also wasn't quick to offer criticism.
"Are there any positions that he takes that you think, 'jeez I wish he was different on that?'"
"Actually, no. None comes to mind with that one," Haag said. "But honestly, really more, I hope he does tone down his - he has started toning down his tone a little bit. The fact is that I do still support him either way."
Like most of the young Republican delegates we met, 18-year-old Joel Crank from Colorado offered his support for Donald Trump, with some reservations.
"You know, I think Donald has quite a few things, good qualities he can offer the Republican Party," Crank said. "You know, there are some things -- when he mentioned the ban on Muslims -- that's something that could not happen here in the United States of America. It's kind of ridiculous."
Young voters were courted throughout the first night of the convention by speakers who took the podium.
"For you first time voters--it's important for you to know what it means to be an American," said actor Scott Baio.
"To my generation, that was for ya'll. To the next generation, this is for you. Your war is here," said Marcus Luttrell, a retired U.S. Navy SEAL.
"We need new programs to help the poor and opportunities to challenge the young," Melania Trump said.
But this group of young delegates, not easily moved by rhetoric, offered some sentiment of their own when it comes to the direction of the party they've just joined.
"Do you have a vision for what the Republican party of the future looks like?" Rocca asked.
"A tolerant party, inviting party to everyone, all groups, all ages, all ethnicities and that's the type of party I would like to see in the future," Laquerre said.
"You know there is a saying about the youth -- 26 percent population, 100 percent future," Flores said. "Without the Republican party learning to grow and bring in that youth, there really is no future."
