"We really like the idea of sanity," 18-year-old Connor Fleming of Greeley said.
Fleming and his mother found out about the Denver event on Facebook.
Fleming was holding a sign that said "Take a deeeeeeep breath," referring to the ads being run by politicians.
"We're all sick of the negativity," Fleming said.
"What we want to do is get a constructive dialogue going and that's what this rally is about; it's about the conversation that has to happen before America starts moving forward and leaving these attack ads in the past," Denver Sanity Rally event organizer, Kiera Havens, said.
Another participant, Amy Scott, held a sign that said, "If you have nothing good to say, be quiet."
"We need maybe a change in how elections are allowed to be run, we wouldn't allow kids to do this in a school," Scott said.
"I think it's a repeating theme in regards to talking bad about others versus supporting what you do, and what you can do right versus bashing on others," Theresa Odello said.
Gretchen Peters was in attendance with her two daughters.
She's hoping the tone of elections will change before her daughter is old enough to head to the polls.
"I think there's a lot of things that need to change about the way we do politics in this country, and I hope that people, through events like, this will start making that change," Peters said.
