Third-party votes in 2012 are allocated from certified county totals by this place's share of each county's two-party vote — that cycle's precinct source records two-party splits.
These Census-place returns are modeled candidate-vote estimates on Census boundaries unless a row explicitly says certified. They are not automatically the official city or town return.
† 2004 sub-county results are estimated: the source reported that cycle at county or municipality level (COVID-era consolidated reporting), so block-level detail is interpolated from adjacent cycles and scaled to certified totals.
