Keeping with the national trend so far, Obama appeared popular among the youngest members of the crowd.
"He's visionary," said Diamond Head resident Jahmelia Lindsay, 25, who showed up to participate in her first caucus last night.
"I like Hillary, but the main difference is that she voted for the war in Iraq," Lindsay said. "(Obama) strikes me as a man of integrity. He excites me as a candidate."
Ala Moana resident Arika Trimnell, 21, who said she is "disappointed with the political scene," stood in line for 1.5 hours to cast her ballot for Obama.
"He's a fresh face, and we need change," she said, waiting in the last of the line to get into the cafeteria. "He's young, and new to the game, but I think that's what we need."
"There are so many varieties of people here," she added. "They're all willing to stand in this long, ridiculous line to make their voices heard. That's a great thing."
People of all ages sported Obama t-shirts and stickers to show support for their candidate.
"It's beautiful," Lindsay said, looking around at everyone standing in line. "I feel like I'm a part of history."
