The Proportional House — mapping the U.S. House under proportional representation.
What if every state split its electoral votes in proportion to its popular vote instead of awarding them winner-take-all? Applied to all 13 presidential elections from 1976 to 2024 (Sainte-Laguë allocation), the proportional leader differs from the actual winner in 2000 and 2016. In four of the thirteen — 1992, 1996, 2000 and 2016 — no candidate reaches 270, which under the Twelfth Amendment would send the election to the House.
