I think it’s fairly common to not translate the initials for political party names. Most English commentary I’ve seen uses just the initials. That said, it is a little weird they translated the names and used the initials at the same time.

I can guarantee you that most of the right-to-travel people are also 100% against taxes of any kind. I have a coworker who believes no one should need a license or car registration and is also fully against any kind of taxes whatsoever. If you mention public roads he just says “we made do without them before”.
