Coverage and interpretation notes

  • Historical geometry is independently versioned

    The map uses a checksum-pinned, election-date geometry build while Electoral College allocations remain traced to the NARA fact tables.

  • County detail begins in 2000

    County-level popular-vote detail is available only for 2000 through 2024. This election has state-level Electoral College coverage.

  • Available and cast electoral votes differ

    The constitutional majority threshold uses the available Electoral College total, while the recorded presidential allocations reflect votes actually cast.
