  "alt": "Seven stacked distributions of county margins relative to the national margin, one for each of 1876, 1904, 1940, 1976, 2000, 2016 and 2024, weighted by votes and labeled with the share of votes within {fact:band} points of the national margin. The 1976 ridge has the largest share, {fact:near5_v_1976}, and the 2016 and 2024 ridges have longer tails on both sides, with {fact:near5_v_2024} within {fact:band} points in 2024 and {fact:near5_v_2016} in 2016.",
  "caption": "The figure beside each year is the share of votes cast within {fact:band} points of the national margin: {fact:near5_v_1976} in 1976, the most of the seven elections, and {fact:near5_v_2024} in 2024. Each ridge is one election, and its height at a point is the share of votes cast in counties whose margin, relative to the national margin, falls in a bin of {fact:bin_width} points, on one height scale for all ridges. Red fill is more Republican than the nation and blue fill more Democratic. Ridge heights depend on the bin width (in bins of {fact:bin_alt} points the 1940 ridge is taller than the 1976 ridge), so compare the labeled shares and not the peaks.",
