Proposed districts, 2024 presidential result
Each state, with its number of seats after the 2020 census. Click one to zoom to it.
How the proposed districts compare with the lines actually used, measured on the presidential vote so candidates and incumbency don’t muddy the comparison. Every measure uses the two-party vote.
Margins are the Republican share minus the Democratic share of all votes cast. R+8 means the Republican won by 8 points; the map shades from D+30 to R+30 and saturates past that.
Implied House results. Redrawn districts never held a House election, so each one starts from its own presidential margin and adds a swing: how far House candidates ran ahead of or behind the top of the ticket. Part of that swing follows the incumbent most likely to run in each redrawn seat, so a strong or weak candidate’s showing carries over with them, and the rest is the average across every real district its voters came from. Each real district is paired with the one redrawn seat that keeps the most of its voters; seats left without a clear pair are treated as open. The two halves count equally. Each year is measured against the most recent presidential race (2016, 2020 or 2024), and races with no Democrat-vs-Republican matchup borrow the state’s average gap.
Matching voters between old and new lines uses counties (state House districts in Kansas), rescaled to match each district’s exact presidential totals, so it’s approximate in big metros and in New England.
