Mexico's Morena loses 10 points in polls, still leads opposition

Mexico's ruling party Morena has seen its support drop by roughly 10 points over the past year, though it retains a lead of three times or more over any opposition party. The decline is notable but does not yet threaten its dominant position, which includes the presidency, federal legislative majorities, and most governorships. The trend suggests erosion of support but no imminent loss of power.
