Overview
- Parties have built more than 200,000 combined WhatsApp subscribers and are issuing timed 'missions' that tell supporters to share, repost or comment on specific posts to increase their algorithmic visibility.
- Vox leads the field with roughly 85,000–90,000 channel followers, PSOE and Frente Amplio each have about 55,000–56,000, Podemos around 27,000, and the Partido Popular trails at about 7,300 with weak engagement.
- Campaign teams openly cite Brazil's 'Ejército de Lula' as a blueprint after that channel grew from tens of thousands to millions and helped amplify pro‑Lula messaging during the runoff.
- Legal and reputational risks have risen as AI‑manipulated images and videos appear in the campaign; Begoña Gómez has filed a complaint over impersonation content that has reached the courts.
- Parties are combining WhatsApp pushes with high‑reach influencers and podcasts such as Jordi Wild to target young voters, a move experts say can amplify reach but cannot substitute for candidate strength or traditional fieldwork.
