Since I basically live under a rock, passing on all pop culture and instead watch an inordinate amount of dreary political videos that make one ever despondent for the future of the world, I had no idea this was going on and has been going on long before Trump got shot (or not) and Biden finally acquiesced. An entire generation of younger Americans waiting to be represented by someone of their time. And now it's here.
And KamalaHQ has embraced all of it, with her social media now the lime green of Brat, Instagram here, Twitter here.
