This ad was issued by one of those "unaffiliated" groups that the Supreme Court recently gave carte blanche to. The basic ground rules is that the party/candidate is absolutely prohibited from coordinating with the group. Nearly all of these groups are GOP leaning, and when any criticism of their ads arises the standard GOP response is "we didn't publish that ad and we are prohibited by law from dictating policy/ads with that group." Do the GOP shills honestly believe the law and rules are different when applied to the Democrats?
Welcome to the Wild West of political ads. The GOP and their backers actively sought this, they are hardly in a position to complain when the arrows come flying their way.
You made your bed, now you have to lie in it-without whining, please.
