Sitai is an SC-reserved rural border-adjacent Assembly constituency in Cooch Behar district, combining agrarian settlements, minority-dense rural pockets, mixed gram panchayats, and riverine belts. Electoral outcomes are shaped by SC consolidation depth, minority alignment strength, agrarian welfare mobilisation, and border-sensitive turnout elasticity. Psephologically, it functions as a bloc-layered rural constituency with medium volatility influenced by mobilisation symmetry and issue-triggered participation shifts. Across the 2019 Lok Sabha, 2021 Vidhan Sabha, and 2024 Lok Sabha elections, voting behaviour demonstrates consolidation stability in SC belts with margin compression driven by minority alignment and border-belt variability.
