First round, voting intention
Our reading of this poll
Since the pollster’s previous wave (July 24, 2026), same lineup:
- Le Pen 30% → 31.5% (+1.5 pt)
- Glucksmann 10% → 11.5% (+1.5 pt)
- Retailleau 10% → 9% (−1 pt)
House effect: on the same lineups, Cluster17 usually puts Mélenchon 2.8 pts higher, Le Pen 2.8 pts lower and Philippe 1.1 pt higher than other pollsters (10 comparisons within 60 days). Not an error: each pollster has its method, and our average accounts for it.
