On Tuesday, Cruz released a video showing eight former Ron Paul liberty movement supporters — a number of them from Iowa — who are now backing Cruz. The campaign announced that former Congressman Bob Barr will chair a Liberty Leaders for Cruz” coalition comprised of libertarian-leaning Republicans.

As Paul’s campaign has floundered and Cruz remains in the middle of the pack, Cruz’s campaign has made the case to Paul supporters that the Texas Republican can remain in the race for a long time — and that while he does, he will espouse libertarian principles. At rallies this summer, Cruz has evoked the Fourth Amendment, railed against the Fed and talked about his efforts to end the bulk government collection of metadata.

In the video, Cruz’s supporters talk about how both Pauls endorsed Cruz’s 2012 Senate run and said they believe he has held positions consistent with the liberty movement, including a reluctance to send boots on the ground to Syria and support for Rand Paul’s bill calling for an audit of the Fed.

“He’s really picked up the mantle of Ron Paul in many ways,” Joel Kurtinitis, the founder of Liberty Iowa and Ron Paul’s 2012 regional director, says in the video.
