  "alt": "Line chart of the share of two-party votes cast in far counties, 1868 to 2024, for all counties in each election and for a fixed panel of counties that report in every election from 1868. The line for all counties is lowest in 1976, the panel is equally low in 1916 and 1976, and outside the third-party years both are highest in 2016, 2020 and 2024. In 1976 the shares are {fact:far_v_1976} for all counties and {fact:pan_far_1976} for the panel; in 2024 they are {fact:far_v_2024} and {fact:pan_far_2024}. A second view adds a panel from 1872, whose share is {fact:pan72_far_1976} in 1976 and {fact:pan72_far_2024} in 2024.",
  "caption": "The dashed line follows the same counties in every election, so counties created or entering the returns later cannot move it. Both lines have their low in 1976, where the panel ties 1916 at one decimal, and outside the third-party years both are highest in 2016, 2020 and 2024. The panel lacks Florida, Mississippi, Texas and Virginia, which have no county returns in 1868, and holds {fact:cov_panel_1868} of the votes cast in 1868 and {fact:cov_panel_2024} of those cast in 2024. For a panel, a county is far when it lies {fact:cut} points or more from the panel's own margin. Shaded columns mark third-party years, listed in the text.",
