The Democrats triumphed in Arizona this November, electing the governor and the secretary of state, and reelecting senator Mark Kelly --in what used to be a red state. But then Senator Kyrsten Sinema quit the Democratic Party, and Progressives moved towards a primary election to challenge her. On this week's podcast, Steve Phillips explains how the victories happened, and what's to be done about Sinema.

Also on this episode of Start Making Sense– the largest strike in the nation entered its fifth week. 36,000 grad student employees of the University of California –including teaching assistants– are not grading final exams. The union agreed to mediation—which seems unlikely to succeed. Nelson Lichtenstein has our update.
