Nuevas Ideas maintains overwhelming dominance in legislative preference polls ahead of the February 28, 2027, vote, projected to secure the large majority of the 60 Assembly seats and leaving the contest for second place fragmented among smaller opposition parties. Recent developments include the Tribunal Supremo Electoral's official call for the election in late September 2026, the opening of candidate registration through November, and internal primaries that produced slates for PCN, ARENA, Vamos, and others. Polling shows these parties each drawing low single-digit support nationally, with no consolidated challenger emerging. Trader pricing on the second-place outcome reflects this uncertainty and the limited structural path for any one opposition party to consolidate enough departmental or overseas votes to separate from the pack before the campaign intensifies.
