Columbus, OH · how this place’s counties split between candidates 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 there is no roll-up above it. Each cell counts how many of this place’s counties a candidate led — a count of records, not a vote total. Who led the place as a whole is not knowable from these returns, because county rows carry a leader and a lead but no per-candidate votes.
Presidential nominating contests in Columbus, OH, 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.

Columbus anchors Ohio's fastest-growing metro, where Franklin County's leftward shift since 2016 has made the area a genuine swing zone — driven largely by demographic change around Ohio State and a booming professional class.
Across the recorded series it reached a Democratic high of 15.2 points in 1912 and a Republican high of 36.0 points in 1984. Between 2020 and 2024 the metro moved 3.2 points toward the Republican candidate; the 2024 margin was 5.0 points.
A population of 2,175,788, a 68% non-Hispanic-white share, and a median household income of $84,300 describe the metro. The metro's voting pattern over the last decade is most similar to that of Kansas City, MO-KS and Baltimore-Columbia-Towson, MD.
