With Sen. Rand Paul's (R-Ky.) exit from the 2016 Republican primary, Texas Sen. Ted Cruz hoped to absorb all the of the Kentucky Senator's supporters by casting himself as a libertarian. There's just one person standing in the way, former Rep. Ron Paul.

According to Politico, the elder Paul bashed Cruz during a Fox Business interview, saying he was "no libertarian" and not much better than Hillary Clinton.

“You take a guy like Cruz, people are liking the Cruz," Ron Paul said on Varney & Company Friday. "They think he’s for the free market, and he’s owned by Goldman Sachs. I mean, he and Hillary have more in common than we would have with either Cruz or Trump or any of them so I just don’t think there is much picking.”

Ron Paul said that of all the candidates running, socialist Sen. Bernie Sanders (I-Vt.) was the most free market.

“On occasion, Bernie comes up with libertarian views when he talks about taking away the cronyism on Wall Street, so in essence he’s right, and occasionally he voted against war,” the former Texas congressman said.

"It's hard to find anybody -- since Rand is out of it -- anybody that would take a libertarian position, hardcore libertarian position on privacy, on the war issue and on economic policy," Ron Paul continued. “So I always say: You can search for a long time, but you’re not gonna find anybody in the Republican or Democratic primary that even comes slightly close to ever being able to claim themselves a libertarian."
