Morena holds a commanding 77 percent implied probability in the Sonora Congress Election Winner market, driven by the party's sustained dominance in state legislative contests and alignment with national trends favoring its platform on social spending and regional development. This positioning builds on strong results in prior cycles, where Morena expanded its presence across Sonora's districts amid high voter turnout in key areas. Trailing parties including MC at 11.5 percent, PAN at 7 percent, PT at 6.2 percent, and others below 4 percent face structural challenges from fragmented opposition and limited recent momentum. No major electoral reforms, candidate announcements, or polling shifts have emerged in the past month to narrow the gap, though nomination deadlines and coalition talks remain potential near-term catalysts before the vote.
