Gary Johnson in The Los Angeles Times

On Principles & Values: Only third-party candidate on the ballot in all 50 states

Johnson has been absent from the stage in all three presidential debates because he's unable to meet the national polling threshold of 15% in five major national polls. Johnson said if he were allowed to participate, he could, perhaps, force Clinton & Trump to "actually talk about issues, instead of seeing them talk about how they're going to kill one another," Johnson said.

Johnson, who has done well with millennial voters, has sought to shore up that support by reaching out to young people who backed Bernie Sanders. This week Johnson released a campaign video highlighting issues on which he says he and Sanders share common ground--among them, opposition to the Iraq war and marijuana legalization.
