Gary Johnson, the Libertarian candidate for president, believes Ron Paul supporters will gravitate toward him, not Mitt Romney or President Barack Obama.

Johnson, a former New Mexico governor, dropped out of the GOP presidential nominating contest to become the Libertarian Party candidate. Before doing so, he announced his support for gay marriage, becoming the only GOP presidential hopeful to do so. Johnson previously supported civil unions.

(Texas Rep. Ron Paul believes states should decide the issue but is personally opposed to gay marriage.)

In an appearance on SiriusXM's OutQ, Johnson said he would be on the ballot in 47 states and was contesting the other three.

“It looks like we are going to be on the ballot in all 50 states,” he told Michelangelo Signorile. “We are involved in litigation in three states, but we're thinking we have a good case. The Republican Party is trying to thwart us at every turn.”

Johnson added that he expects supporters of Ron Paul – who lost the GOP nomination to Romney – to vote for him, not Romney, whom he described as not conservative enough, or Obama, whom he described as not liberal enough.

“Given the fact that I'm saying the same things as Ron Paul, [and] given my own prognosis back in December that Ron Paul would not be the nominee, who is going to be the spokesperson for the liberty and freedom movement, which is the fastest-growing movement in this country? Right now when it comes to Ron Paul supporters, are they going to vote for Mitt Romney? Are they going to vote for Barack Obama, when I'm an option? I don't think so,” he said.
