Mayer-Rossignol dominates Rouen's election with unprecedented cross-party appeal

Nicolas Mayer-Rossignol leads Rouen's municipal elections with a strong first-round showing. A recent poll places him at 42% of voting intentions, well ahead of his nearest competitor. His broad appeal stretches across multiple voter groups, marking an unusual level of cross-segment support.

The Cluster 17 survey, conducted between March 8 and 10, 2026, sampled 671 Rouen residents, including 504 registered voters. The margin of error for the voter subset ranged from 1.9 to 4.5 percentage points. Mayer-Rossignol's dominance is clear: he secures over 70% of left-leaning voters, 41% of those focused on solidarity or rebellion, and 49% of multicultural progressives.

His reach extends beyond traditional left-wing supporters. The candidate also attracts 28% of centrists and liberals, along with 22% of sceptics and social patriots. This cross-sector performance sets him apart in a fragmented race. Marine Caron, the centre-right contender, trails at 26%. Her campaign struggles to unite right-leaning and National Rally (RN) sympathisers, limiting her growth. Meanwhile, Grégoire Houdan (RN) and Maxime Da Silva (La France Insoumise) each hold 15% support, rounding out the top four. Mayer-Rossignol's coalition deliberately excludes La France Insoumise, yet his lead remains unchallenged. The last municipal election in 2020 saw Nicolas Rouly (Les Républicains) win, with right-wing forces maintaining control until now. This poll suggests a potential shift in Rouen's political balance.

The results indicate Mayer-Rossignol's strong position heading into the election. His ability to draw votes from diverse segments gives him a clear advantage. If these figures hold, Rouen could see a shift from the right-wing dominance of the past six years.
