25 meetings, Tuesdays and Thursdays. One of them, Tue, Nov 24, meets on Zoom rather than in the room. Tinted days are ones we do not meet — fall break, Democracy Day, Thanksgiving, and the Constitution Day Symposium.

How American elections actually work, taught through the data they produce. Tuesdays we read; Thursdays we put real election data on the screen and work out what it shows — through the 2026 midterms, live.
