Field notes
The forecast view includes projected turnout and expected movement from the 2024 presidential vote, broken out by county, House district, and state. Its source accounting excludes market pages, APIs, data files, and reference sites such as Wikipedia and Ballotpedia. Named contributors and links to research methodology and sources provide context, while the page’s synthetic-preview label limits what can be inferred about the forecasts themselves.
