A handful of newly incorporated limited liability companies is using a huge network of Facebook pages to mount a series of social-media attacks on Republican Party policies, donors, and political candidates, with some of the ads hitting some conspicuously sexist notes.

A pair of posts promoted this week on a Facebook page titled The Keg Bros contained two videos, one attacking Republican megadonor Rebekah Mercer and one hailing Democratic Rep. Tulsi Gabbard. “Hawaii’s Tulsi Gabbard makes us want to go Democrat,” reads text in one of the videos, interspersed with footage of Mike Myers’ Austin Powers mouthing “hot hot hot.” It adds, “America’s voted, and she’s the hottest member of Congress on either side of the aisle.”
