Tlaxcala’s 2027 state congress election, held alongside the gubernatorial contest, features a fragmented field where Morena holds a polling edge near 40 percent but faces coalition negotiations and internal tensions with allies PT and PVEM. Recent surveys show Morena ahead of PRI, PAN, and Movimiento Ciudadano, yet opposition parties remain competitive in individual districts while the current LXV Legislature’s composition and alliance dynamics introduce uncertainty. Trader prices near 48-50 percent for leading options reflect this balance, with potential shifts driven by candidate selections, formal coalition agreements expected by early 2027, and turnout patterns across the state’s 15 districts and proportional seats. The process formally begins in December 2026.
