NECOCHEA — Municipal shared ballot: mayor / council
All 24 provincial jurisdictions are screened; 3,440 current provincial/local or shared-ballot units are registered. Recovered archives now cover all provinces. All 804 previously inaccessible Córdoba tribunal tables are restored, adding local histories and replacing provincial secondary vote transcriptions. Several local tiers have inventories or winner-only evidence without three full returns. Corrientes and Santiago del Estero executive cycles outside the window are excluded. Partial chamber renewals, Santa Fe commune reform, conventions and replacements remain distinct. Older local votes, selected certificates and 2027 office calls remain incomplete. Ten 2023 Catamarca local returns are recovered from DINE provisional table data through exact single-municipality department bridges; they remain excluded from complete-cycle metrics pending final-tally reconciliation.

National polling context: National presidential approval; context for subnational races — AtlasIntel / Bloomberg; fieldwork 2026-07-30 to 2026-08-03. Sample 1,120; reported margin of error ±3.00 percentage points. Earlier comparison wave; named officeholder and question wording retained. Poll report
National polling context: National presidential approval; context for subnational races — AtlasIntel / Bloomberg; fieldwork 2026-08-30 to 2026-09-03. Sample 2,193; reported margin of error ±2.00 percentage points. Approval rose 1.0 percentage point while disapproval fell 4.4 points; approval movement is smaller than the combined reported survey uncertainty. The negative approval balance remains a national headwind for Milei-aligned candidates, conditional on local alliance and incumbent identity. Poll report
One shared municipal ballot is counted once. The council comparison uses 2025, 2023 and 2021; mayor elections are separately identifiable in the retained 2023, 2019 and 2015 returns. Council seats show the renewal cohort. Current control, special events and the 2027 call remain unverified.

Electoral event evidence
Separate source records can belong to the same election cycle. Recounts, runoffs and void returns do not create additional cycles.
