In an opinion newsletter, Frank Bruni surveys the 2028 Democratic field after Democrats' big midterm wins, weighing Kamala Harris, Gavin Newsom, Pete Buttigieg, Alexandria Ocasio-Cortez, Josh Shapiro, Jon Ossoff, and others against questions of age, electability, and whether sexism blunted Harris's 2024 loss. He predicts the wave will enlarge an already crowded field, and quotes other writers on Trump's implosion, including Matt Bai, Helen Lewis, and Alexandra Petri's satire of a wounded MAGA stalwart.
