No officeholder observation supplied.

6. Polling context

No local poll supplied.

7. Unresolved issues and sources

Ordinary 2027 cohort provisionally registered from the 70-municipality 2023 election archive. Fontana 2024 replacement is a separate completed event. Final current control and later exceptional calls require review. 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.
