Early projection, based on early and incomplete polling: the likely matchups, each weighted by the betting markets' odds of both nominations, not a result. Each county is its 2024 presidential margin moved by its state's projected swing; set a national vote and every state, district and county moves by the same amount from our projection. Colours run in 100 steps from a safe Republican to a safe Democratic margin. Boundaries: US Census Bureau.
