Rounded approval fell from 48% to 45%, and disapproval rose from 51% to 53%. This supplies a national headwind indicator for Lula-aligned candidates, but Brazilian state coalitions differ and individual state polling takes precedence. Overview values are rounded to whole percentage points.

Early governing-list exposure in Canillo, Encamp, Ordino and La Massana; local coalition re-formation and parish polls required Of all 403 citizens, 35.2% were undecided and 9.6% declined to answer. Reported ±4.95 pp error applies to the citizen sample, not smaller decided-vote subsets or individual parishes. AR+I publishes national-list estimates only because parish samples are inadequate. Fieldwork ended 116 days before the snapshot; local elections are more than a year away. National alliance labels and municipal coalitions differ.
