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.
