Field notes
The homepage displays model projections of about 230 Democratic House seats and 51 Democratic Senate seats, alongside majority probabilities; these are the site's forecasts, not independently verified outcomes. It attributes historical returns to sources including MEDSL, VEST, and the Harvard Election Data Archive, and links to a companion archive for equations, backtests, and data.
