Former New Mexico Gov. Gary Johnson is running for president as a Libertarian, just as he did 2012 when he managed to get 1.2 million votes. Regardless of his chances of a win, Johnson is reaching out to undecided Republican voters who are looking for a third-party option and are unconvinced that Donald Trump is the answer. / AFP / Nicholas KAMM (Photo credit should read NICHOLAS KAMM/AFP/Getty Images)
