presidential primaries
Nominating contests
Connecticut · 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.
Presidential nominating contests in Connecticut, 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.
2020 field
264,416 votes cast across 8 counties reporting. The universe is the party's primary electorate, not everyone who lives here, so this is not comparable to a general-election turnout without that in mind.

“All others” is a residual bucket, not a candidate: it holds every name past the ones listed, including candidates who had already withdrawn but still drew votes. Shares are of the 8 counties reporting, and describe the contest as a whole — not any one county inside it.

2020Democratic primary leaderBidencolor = leader · depth = size of the lead
Every county with reported returns, filled by the candidate who led it — the most recent cycle Akashic carries here. Depth is the size of the lead, not a party margin; the surrounding faint geography is context, not coverage.
A county's fill says who led it and by how much. It does not say how the rest of the field did there — those shares are published statewide only.
