I don't think any organization that considers themselves to be libertarian has ever called Texas a "libertarian state". For example:
>...Texas’ institutions and policies continue to bear something of an old statist legacy. In the Cato Institute’s Freedom in the 50 States study, Texas scores a mere 17th, behind even the southern states of Florida (#2), Tennessee (#6), Missouri (#8), Georgia (#9), and Virginia (#12).

Are there any Texas national or state politicians who are members of the Libertarian Party or even refer to themselves as Libertarian?
