This election in West Bengal is expected to be very tight, and the next state government will probably be formed based on the results from those 57 key seats. Both TMC and the BJP are focusing their energy and money on these swing seats, because in the past the winners only won by a small amount of votes – and a small change in voting numbers could easily change who wins. Plus, legal and administrative issues are adding to the uncertainty.
Close margins define the 57 seats
In 2021, the winners in each of those 57 seats won by 8,000 votes or less (the average winning margin was about 8,000 votes). Nineteen of them were won by fewer than 3,000 votes, meaning they are easily affected by small changes in how people vote and by people voting strategically.
In 2021, TMC won 29 of these seats and BJP won t8. In the very closest of these, BJP won 12 and TMC won 7. Considering TMC had 213 seats and BJP had 77 in the last assembly, these swing seats have the power to completely change the balance of power in 2026.
Geography of the battleground
Most of these seats that could easily go either way are in south Bengal (47 of the 57), with 10 in north Bengal. A large number of them are in the western districts of Purba Medinipur, Paschim Medinipur, Bankura, Purulia and Paschim Bardhaman.
Several local results show just how unpredictable things are. In Bankura, several seats were won by under 7,200 votes, one by just 1,468. In Paschim Bardhaman, Kulti was decided by only 679 votes. Nandigram and the seats near Nandigram are still very important symbols in politics, and they often have winning margins of less than 2,000 votes.
Political dynamics and emerging players
The competition in 2026 looks more split than before. Congress looks likely to fight the election on their own in many places, and the CPI(M) have agreed with the Indian Secular Front on which seats each will try to win. AJUP, a new group, has teamed up with AIMIM, and this adds another level of competition in some areas.
People in the parties understand that even a few thousand votes moving from one party to another could have a huge effect on the result. A leading member of the BJP said that if a few thousand votes shift away from either BJP or TMC, it could decide everything. TMC advisors say that these 57 seats are the most important thing for keeping power or losing it.
Administrative issues and legal backdrop
The way the election is being organized has caused some new problems. On March 25th, the Calcutta High Court said the Election Commission of India’s decision to reject a company’s proposal for election monitoring services was unfair and badly explained. However, the court didn’t cancel the contract, because the voting days of April 23rd and 29th are so close.
I-Net Secure Labs Private Limited, the company who complained about how the company for live video and CCTV was chosen, brought the case. The court said the public’s need for things to work was more important than the company’s complaint and didn’t stop the work orders, but what the court said does make you wonder about how fairly the contracts were given out and how confident people will be in the vote.
What to watch before polling day
Changes to the list of voters, how people locally feel about the current government, and who the parties choose to stand for election will be very important in these 57 swing seats. Parties will do a lot of very specific campaigning aimed at particular groups of people, get their supporters to the polling stations, and talk to communities where even a small number of votes could determine the outcome.
We can expect the election process itself to be closely watched, from the monitoring to the voter lists. Because of examples like the Dinhata by-election (where the result was reversed) and other very close wins, making sure supporters actually vote and small changes in voting numbers could be what ultimately decides the outcome of the West Bengal election in 2026.
