On most economic issues, Cruz is a Conservative Libertarian, which logically should make him a defender of free trade. However, for reasons of pure electoral expediency, he has supported the Reactionary position over the CL position on two important issues: immigration and protectionism.
This wouldn’t be a big deal if Cruz could pivot back to the center in a general election, but his entire campaign shtick revolves around his supposed ideological incorruptibility, so it is hard to see how he can walk it back.
