How this is measured
Combined career popular votes are summed across the 4 family members we track, each counted once across every presidential, U.S. Senate, governor, and U.S. House election in our data. Family membership is hand-curated and verified against primary sources, never matched by surname alone, so unrelated namesakes are never folded in. A vote for a presidential ticket counts for both the president and the vice-presidential candidate, matching how each profile reports its own totals.
