I probably don't agree with Brett Kavanaugh but I do certainly believe he was subjected to an extended and transparent political smear campaign. I don't think it is a good picture for an organisation for civil liberties to partake here and if they are connected to that it is a bit worse than a bad look.
So its a bad look for a special interest group to pursue that interest when a Republican operative is involved? I don’t understand how the two are related. Are you saying Brett Kavanaugh was wrongly construed, that he will support civil liberties? Seems like money well spent by the ACLU.
I don't see any possibility how the media campaign against him can be construed as a gain for civil liberties. Especially like you almost admit that it wasn't about his failures as a person and just politically motivated. This is independent from how well Brett Kavanaugh will later defend civil liberties or not.
How is it independent? The reader can decide if he's morally qualified or not, but he had a long judicial record to rely upon for the ACLU to decide that he wasn't a friend of civil liberties.
