In the previous assembly election, these 37 seats once again aligned with the outcome. The Trinamool Congress secured 23 of them, while the BJP won 14, reflecting the broader victory margin in the state.
The BJP performed strongly in North Bengal and parts of the Ranaghat and border belts, while the Trinamool dominated large stretches of Nadia and urban pockets in North 24 Parganas. This split highlighted regional contrasts but ultimately favoured the ruling party.
These seats, spread across North Bengal, Nadia and North 24 Parganas, have consistently mirrored the broader political mood since 1977. Whichever party manages to secure a majority here has almost always gone on to win power in the state.
The bellwether seats for West Bengal
The 37 key constituencies that have long acted as electoral bellwethers in West Bengal include Alipurduars, Kalchini (ST), Darjeeling, Balurghat, Tapan (ST), Raiganj, Karandighi, Islampur, Chopra, Goalpokhar, Chakulia, Karimpur, Tehatta, Palashipara, Kaliganj, Nakashipara, Chapra, Krishnanagar Uttar, Nabadwip, Krishnanagar Dakshin, Santipur, Ranaghat Uttar Paschim, Ranaghat Uttar Purba, Ranaghat Dakshin (SC), Chakdaha, Kalyani (SC), Haringhata (SC), Bagda (SC), Bangaon Uttar (SC), Bangaon Dakshin (SC), Gaighata (SC), Swarupnagar (SC), Baduria, Habra, Ashoknagar, Amdanga and Bijpur.

In the 2021 assembly elections, the Bharatiya Janata Party dominated the North Bengal stretch, winning Alipurduar, Kalchini, Darjeeling, Balurghat, Tapan and Raiganj.

The party also performed strongly in the Nadia region, winning a clean sweep across Karimpur, Tehatta, Palashipara, Kaliganj, Nakashipara, Chapra, Krishnanagar Uttar, Nabadwip, Krishnanagar Dakshin and Santipur.
The Ranaghat–Kalyani belt saw a mixed outcome, with the BJP winning Ranaghat Uttar Paschim, Ranaghat Uttar Purba, Ranaghat Dakshin and Haringhata, while the Trinamool held on to Chakdaha and Kalyani.
