Several attendees said that after the attempted assassination attempt, they expect to hear about unity and see a different side of Trump.

"I expect to see a risen man, a man who has had an encounter, a transformative encounter, with the divine, with death and with God, and God won," said delegate Minerva Diaz. "So I expect to see a transformed man who now is going to embrace all the people who love him, every person of every nation."

"I am already hearing these messages of unity, these messages of hope, these messages of the principles that will bring us to that culmination of the unity," said delegate Betty Chu.

"I'd like to hear how he's going to continue to unify our country, as he's been doing so well," said one woman. "And I think he has given us the opportunity to bring back our country, and he's going to tell us how he is going to do that."

Another said she expects the stadium to be on "fire."
