I finally got the ad to pop up again (it’s a video ad that pops up in the bottom corner of some websites). Seems to be from the “Protecting Our Values” PAC, which is apparently a Democrat super PAC primarily focused on helping the Independent Alaskan US Senate candidate oust the incumbent Republican. I guess they decided to expanded their cause.
I actually feel better knowing it’s a Democratic PAC – Democrats thinking some Republicans are complete imbeciles is par for the course. The alternative was just too depressing to contemplate.
