Well they can't be very liberty friendly (or Constitution friendly either) since they are backing the candidate that voted to reauthorize the anti-liberty, unConstitutional Patriot Act. Rand Paul BTW single handedly killed the Patriot Act.
No, he didn’t. He opposed the Patriot Act. He has talked about that in his campaign.
Cruz actively supported Patriot Act revisions and replacements that would make it much more pro-liberty and still render it effective in fighting terrorism.
