These students and high-school pupils are the youngest delegates to the Democratic Party convention, joining a flood of young people under the age of 30 who have swollen the packed convention center.
"Maybe because he looks younger than his actual age, Barack Obama gives young people hope that they can achieve the political representation that they don't have right now," said Idaho student Julian Langness, 22.
"You often hear that women, racial minorities or homosexuals are under-represented in US politics, but by far, it's mainly young people who suffer from it."
"Barack Obama made politics exciting again," he added.
The law student, from a conservative rural northwestern state who hopes in 2010 to stand for office in the Idaho Congress, says he's against the death penalty, and in favor of abortion rights.
But he also believes in the right to bear arms "because when you live 30 miles from the next police station, you have to be able to defend yourself."
The youngest delegate to the four-day political jamboree is 17-year-old David Gilbert-Pederson from northern Minnesota, the state which next week hosts the Republican Party's convention.
Ben Goodman, who is just a year older, will on Saturday head from Denver to start his degree in political sciences.
He told AFP that he has been an Obama fan "since January 2007," even before the Illinois senator declared his candidacy.
He said Obama had a clear message on issues close to his heart such as health insurance arguing "Obama's plan is "much more practical" than Clinton's.
"Since I was a little kid, I wanted to be in a convention. Being in this place is very surreal," said Goodman from Kennebunk, Maine.
He also approved of Obama's opposition to the war in Iraq.
"I was convinced by Colin Powell," the former secretary of state during President George W. Bush's first term who in 2002 insisted before the United Nations that then Iraqi dictator Saddam Hussein possessed weapons of mass destruction.
But he know believes that the war in Iraq has been a failure. "We have to pull from Iraq to take care of problems at home," he said.
"I'm Jewish and I'm of course a strong supporter of Israel, but I don't believe that the war in Iraq has made US and Israel more secure."
Stephen Ferguson, 19, from Burbank, California, was eagerly awaiting for the speech by Hillary Clinton, saying "my vote won't go to him [Obama], I was elected to support Hillary.
Young delegates, who've grown up with the Internet, can be seen busily texting in the convention corridors, keeping up with the daily buzz on their Blackberries and iPhones.
Some of them have been regularly posting on their blogs from Denver, keeping in touch with voters back home through messages and photos.
Goodman has made his Facebook social networking site one of his key convention aides.
Facebook "is a great organizing tool, we can schedule an event, and that's how I got to meet hundreds of people sharing the same political interests," he said.
