I prefer blue maga, but it's someone who thinks the world can made great by the liberal side of the American binary system. Despite the fact that civil "rights" which were fought for have been systemically torn apart by a ratchet effect and a forever shifting Overton window that the democratic party has been explicitly engaging in.
They think the DNC can be trusted, that the system is not broken, and that change can be created from within the DNC/RNC monopoly by working with it. Not that we are a near fully-captured oligarchy with low education masses that are easily manipulated by media propoganda.
