Jerry Ratcliffe @jerryratcliffe.net · 08/08/2026I fear sensible dems like @petebuttigieg.bsky.social will spend forever in the political wilderness because DSA and affiliated candidates will keep losing elections by moving the Overton window away from the mainstream with boutique nonsense, and continually hand the right wing easy wins. 020

Jerry Ratcliffe @jerryratcliffe.net · 12/05/2026With fewer reviewers and AI helping generate more academic articles, anticipate more desk rejects.
