Several candidates were in Boulder on Tuesday for a presidential debate you may not have heard about.

It was not televised on a major network and the crowd was sparse, but actor Ed Asner of Mary Tyler Moore fame moderated the debate between third party candidates.

At this point in the process the candidates know the odds.

One even admits that he won't get a vote from his wife, his son, or himself.

"We ask people not to vote for us because we are fully aware that you are wasting your vote when you are voting for us in our current system," Frank Atwood, a presidential candidate for the Approval Voting Party said.

"I'm just trying to get my message out there so people know that I exist," Lily Tang Williams, Libertarian U.S. Senate candidate, said. "And I think I am the best candidate for this race."

"There's no point if they don't let you debate," presidential Reform Party candidate Rocky De La Fuente said. "There's no point if they don't give you an opportunity."

"They say if you vote for a third-party candidate you're throwing your vote away," voter Ava Philppus said. "And I say as long as we have that mentality then we are never going to change the system."

It's going to take a massive action by the people," presidential Constitution Party candidate Darrell Castle said. "That's one of the reasons why I wanted to come to this debate to talk about that."

The Free and Equal debate was also held in 2008 and 2012.
