Sen. Bernie Sanders (I-VT) is maintaining his support for Joe Biden even as cracks start to form in the progressive coalition standing with the president.

Sanders, who cemented his status as the leader of the progressive movement by challenging Hillary Clinton and then Biden for the presidential nomination, has since emerged as an establishment ally. He, along with “Squad” Democrats including progressive icon Alexandria Ocasio-Cortez (D-NY), have resisted calls for the president to drop out of the 2024 race following a disastrous debate performance that fueled concerns over his mental fitness.
