On Sunday, organizers say about 1,600 people came to Sunnyside High School to see a campaign event for Hillary Clinton here in Tucson.
"My mom said, like 'I've never been the first for anything, so it's kind of exciting," said Clinton supporter Robert Deleon.
Deleon and his mother were the two first people in line for the event, showing up on Sunday around 9:30 a.m.
"We were looking for the line and then we walked here," Deleon explained. "And the auditorium was open so we just walked in and they were still setting up."
But, Deleon was not alone for very long as the lines began sprawling and snaking around the building.
A majority of the crowd were supporters of the democratic front-runner.
"I really have a lot of respect for both he [Bill Clinton] and Hillary," said Clinton supporter Patricia Koch.
Koch told KGUN9, that she was looking for a chance to hear more directly from those involved.
"I would like to have my concerns and questions answered and I think they will be," Koch said.
But, among the crowd, a few people stood out to stand against the Clinton campaign.
"America cannot wait - this incremental attitude for change." Barbara Cihlar said while holding a sign. "We can't wait. The American people need help yesterday we need help now."
Cihlar said she was a little nervous to face the supporters, but she held her sign for what she believed in.
"I'm very upset. So, this is just me trying to use my voice and that's all I can do," Cihlar explained. "I'm an American as well as everyone else here and I care."
But, this scene of opposition, a stark contrast to rallies yesterday for Republican front-runner Donald Trump.
"I haven't gotten sucker punched yet... So, that's exciting," Deleon laughed.
He says the heat only came from the sun, not from the crowd of people around him.
"It's kind of disheartening when you see rallies and you are seeing pepper getting punched left and right and a lot of fear mongering," Deleon said. "But here, it's been peaceful... everyone's been pleasant."
