Meet Gary Johnson, the Third Party Presidential Candidate Who's (Literally) Kissing Off Donald Trump

Former New Mexico gov. Gary Johnson is new to the presidential race, but it seems he's already vying for a special Donald Trump nickname.

Johnson was selected as the Libertarian candidate on Sunday at the party's convention in Orlando, Florida, and former Massachusetts gov. William Weld was picked as his running mate, according to CNN. During the convention, Johnson fired shots at the presumptive Republican nominee, calling his immigration policies "just racist."

Appearing on CNN, Tuesday, Johnson added that he's ready for whatever attacks Trump may launch at him. "I think that they've already started coming, so you know, Donald," he said, before blowing a kiss at the camera.

Johnson, 63, has been the party's nominee once before, landing on the ticket in 2012 – despite backlash from the party's radical wing, according to CNN. He received 1 percent of the vote in that year's general election.

"This is another voice at the table," Johnson said on Sunday after charging that the Libertarian party could poll well amid disapproval of Trump and Hillary Clinton.

Trump addressed Johnson's nomination during his Trump Tower press conference on Tuesday.

"He got 1 percent of the vote last time, I watched that whole situation," Trump, 69, said. "It was really pretty disgraceful... I think he's a fringe candidate, you wanna know the truth... And your second, Weld, when you do a little research on that I think it's not gonna be a factor."
