The large field of over two dozen registered candidates for Arequipa's 2026 municipal mayoral race has produced a fragmented contest, with leading contenders Ricardo Alfredo Ramírez del Villar Llosa, José Miguel Briones Silva, and Tomás Job Delgado Zúñiga trading narrow edges near 34-36% in trader pricing and recent polling. Current mayor Ruccy Judith Oscco Polar and other regional figures remain competitive amid ongoing surveys through late August. This distribution reflects Peru's municipal rules allowing broad participation, limited early differentiation on local issues such as infrastructure and services, and the absence of a dominant frontrunner or major campaign shift in recent weeks. Scheduled candidate registrations and further polls ahead of the October vote could consolidate support or create separation among the top group.
