Senator Bernie Sanders and Rep. Alexandria Ocasio‑Cortez are pushing progressive candidates in Republican‑leaned House districts that Democrats must win in November. The left argues that universal health care and higher taxes on the wealthy can attract working‑class voters even in red areas. Sanders toured with Michigan Senate hopeful Abdul El‑Sayed in May, signaling a shift toward competitive battlegrounds.

Campaigns such as Randy Villegas in California’s Central Valley illustrate the new strategy. Villegas, a self‑described populist supporting Medicare for all, faces incumbent Republican David Valadao while Republicans fund a more moderate Democrat to create an easier opponent. Villegas maintains his message of refusing corporate money and tackling health issues like valley fever resonates across party lines.

Sanders has now issued 16 congressional endorsements, with seven in races deemed competitive—a sharp rise from four in the 2022‑24 cycles. He argues that standing up for the working class is a universal winning formula, while centrist groups warn such left‑leaning bids risk producing unelectable targets, citing past defeats of progressives in swing districts. The progressive push thus tests the Democratic calculus ahead of the midterms.
