Don’t chalk Rand Paul up as a libertarian just yet.

Gary Johnson, the Libertarian Party’s 2012 presidential nominee, said the Republican senator from Kentucky is just that – a Republican – but definitely not a libertarian.

While Paul may be the most libertarian-minded candidate in the field of prospective GOP presidential candidates, Johnson said, Paul doesn’t fit the libertarian mold on a host of issues: from abortion to marriage equality to immigration and marijuana.

“He’s a Republican,” Johnson said.

“Great, I mean terrific,” Johnson said sarcastically. “I mean, the most libertarian candidate that Republicans may end up fielding.”

Paul has even sidled away from his libertarian foreign policy views, ​shying away from his isolationist views in favor of a more nuanced foreign policy that would better fit the mold of a Republican primary.
