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. Missing older local results in several provincial datasets, full seat proclamations, intervened/replacement contests and dated coalition control. Many municipalities vote separately from provincial election day. Final 2027 calls remain subject to official publication. Ten Catamarca 2023 local returns now have primary provisional counts; final certification and older cycles are still missing. DINE 2015 download has no Catamarca local records. Entre Ríos final national consultation warns that foreign-voter tables are excluded. Neuquén final-file links returned access-denied responses; several older links point to private or defunct hosts.
