The AG in Arizona HAS pledged not to prosecute nor enforce this absurd law. The AG, by the way, is a she, not a he.
I expect she will not.
But, if the next governor of Arizona is a Republican, she will be out of a job...and the new AG, male or female, will undoubtedly be willing, happily, to enforce it to the letter.
The AG should not be able to choose the laws they enforce or do not. It is authoritarian bullshit.
