"I want to take this opportunity to announce my candidacy for president. I am hoping to get the Libertarian nomination for president in 2016," Gary Johnson said in his TV announcement.
Johnson has been a harsh critic of Republican front-runner Donald Trump already in the last few months, saying the fellow businessman-turned-politician appeals to "racist" voters.
He also touted his ability to potentially win votes from both Democratic- and Republican-leaning voters, but that his ultimate goal is to run a reasonable campaign.
"On my deathbed, I'm hoping that I look back and believe that I was the voice of reason in all this, regardless of how many votes I end up garnering," he also said.
He ran for president in 2012 as well, initially seeking the Republican nomination. He later switched parties and became the Libertarian nominee instead. His ticket, which garnered more than a million votes on Election Day 2012 -- almost one percent of the popular vote -- became the most successful third-party ticket since Ralph Nader's run in 2000.
