presidential primaries
Nominating contests
Sierra Vista-Douglas, AZ · which candidate this place backed in each party’s presidential nominating contest, cycle by cycle. A primary is a contest inside one party, so it has no Democratic–Republican margin and is not part of the general-election record above.
Akashic reports votes cast, not delegates awarded. The two can disagree: Clinton led the 2008 national primary popular vote by less than half a point and did not win the nomination.
Primary returns are published at county grain, and this place is a single county: Cochise County, Arizona. The figures below are that county’s, which is the same territory — not a larger unit standing in for it.
Presidential nominating contests in Sierra Vista-Douglas, AZ, by party and cycle.
○no contest record — Akashic holds no result for that party and cycle here. It is not a claim that no contest was held. Telling apart a contest that was cancelled, one that went uncontested, and one simply not yet ingested needs a nominating-contest calendar, which is a separate ingest from results and does not exist yet.
Republican presidential primaries are not yet ingested — the Republican series runs from 1856 and is in scope. The row is kept so its absence is visible: a Democratic-only panel would otherwise read as though no one else held a contest.
Akashic carries 10 states for 2012 and 3 states for 2024. Cycles in which an incumbent president seeks renomination are thin by nature — few states run a contested primary — so a sparse column is politics, not a hole in the record.
County returns carry a leader and a lead over the runner-up, and nothing more. The full candidate field with vote shares is published at state grain — follow a cycle above to the state contest for it.
