Participation
Turnout and midterm durability
Participation measured against the same-year citizen voting-age population. Audited cycles count total general-election participants — ballots or participating voters, not presidential candidate votes. Cycles before 2016 predate that series and are derived from the certified presidential returns instead; they are marked everywhere they appear and are excluded from the figures below.

Sources and methods
Audited cycles (2016, 2018, 2020, 2022, 2024) count total general-election participants against the same-year CVAP special tabulation, each cell carrying its own numerator and denominator quality grade. Derived cycles (2004, 2008, 2012) come from the certified presidential returns on this page over the ACS 5-year CVAP series, so they measure presidential votes cast rather than ballots — a floor on participation. Where a derived cycle predates the ACS its denominator is extrapolated rather than read, and says so on its own line below. They are shown for the longer arc and are excluded from the drop-off, excess-drop-off, and 2026 scenario figures above.
2024: numerator source 160, denominator source 157; estimated total ballots; preferred-county:block-reference-presidential-or-cvap-weight:v2; allocation share 100.0%; series 323/229.
2022: numerator source 160, denominator source 157; estimated total ballots; preferred-county:block-reference-presidential-or-cvap-weight:v2; allocation share 100.0%; series 322/184.
2020: numerator source 160, denominator source 157; estimated total ballots; preferred-county:block-reference-presidential-or-cvap-weight:v2; allocation share 100.0%; series 321/4.
2018: numerator source 160, denominator source 157; estimated total ballots; preferred-county:block-reference-presidential-or-cvap-weight:v2; allocation share 100.0%; series 320/139.
2016: numerator source 160, denominator source 157; estimated total ballots; preferred-county:block-reference-presidential-or-cvap-weight:v2; allocation share 100.0%; series 319/133.
2012 (derived): Certified presidential returns · ACS 5-year CVAP (B05003); presidential votes cast — a floor on participation, not a ballot count.
2008 (derived): Certified presidential returns · ACS 5-year CVAP (B05003); presidential votes cast — a floor on participation, not a ballot count.
2004 (derived): Certified presidential returns · extrapolated CVAP denominator; presidential votes cast — a floor on participation, not a ballot count; 2004 predates the ACS, so the denominator is a linear back-extrapolation from the 2008 and 2012 CVAP values, not a read figure.

Marietta-Alderwood · 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. The figures below are Whatcom County, Washington, the county containing Marietta-Alderwood — Marietta-Alderwood’s own primary vote sits inside those totals and is not separately reported.
Presidential nominating contests in Marietta-Alderwood, 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.
