Morena holds the leading position in the Tabasco Congress market at 58 percent amid strong recent performance in federal district races, where its alliance secured all six Tabasco seats in the October 2026 vote. Party identification surveys show Morena at 43 percent affinity in the state, well ahead of Movimiento Ciudadano and smaller parties, supported by alignment with federal policies and local infrastructure announcements. The market remains tight because opposition parties such as PRI, PAN, and PVEM register lower single-digit to low-20s support, while multiple smaller options sit near 50 percent, reflecting fragmented challengers and uncertainty over candidate slates ahead of 2027 local contests. Internal Morena dynamics, including factional setbacks for the “Grupo Tabasco” circle, add volatility without yet shifting the overall edge. Scheduled municipal coordination registrations and any shifts in state legislative priorities could widen or narrow the gap before resolution.
