From the Freedom Caucus to the democratic socialists, small groups inside parties can wreak havoc with leaders’ agenda in Congress

A handful of Democratic Socialists of America-affiliated candidates, including allies of Rep. Alexandria Ocasio-Cortez and Sen. Bernie Sanders, are on track to join Congress after the 2026 midterms, with Democrats favored to retake one or both chambers. The piece traces how small, organized ideological blocs, most notably the House Freedom Caucus, have leveraged narrow majorities to extract concessions or topple leadership, citing Kevin McCarthy's 15-round speaker fight in 2023 and his later ouster for compromising with Democrats.

Whether DSA-aligned members carry similar leverage depends heavily on margin size: with some models projecting Democratic House majorities as large as 30 seats, leadership under presumptive speaker Hakeem Jeffries may not need every vote from the party's left flank. The piece notes that organization and cohesion, not just ideological alignment, determine whether a small faction can actually shape legislation rather than simply vote as a bloc without leverage.
