A post-poll analysis of the 2026 West Bengal Assembly Election — written the evening polls closed, April 29, 2026
Voting in West Bengal is over. The 294-seat assembly that will determine whether Mamata Banerjee secures an unprecedented fourth consecutive term — or whether the BJP finally breaks through after 15 years of trying — will be decided on May 4. The data already on the table tells a compelling story before a single vote is counted. But Bengal has a long history of making fools of people who claim certainty about its electorate.
That history demands respect.
The Numbers That Change Everything
Two phases. Two very different Bengals. One election.
Phase 1, covering 152 constituencies across north Bengal, Jangalmahal, Murshidabad, and Birbhum, recorded a final confirmed turnout of 93.19% — the highest in the state’s history since Independence, up more than 8 percentage points from the 84.72% recorded in 2021. Of the 3.61 crore eligible voters in this phase, 3.36 crore actually voted. The district breakdown is striking in its detail: Cooch Behar led at 96.2%, followed by Dakshin Dinajpur at 95.44%, Malda at 94.79%, Jalpaiguri at 94.76%, Birbhum at 94.51%, and Murshidabad at 93.67%.

Phase 2, covering 142 constituencies across metro Bengal — Kolkata, Howrah, North and South 24 Parganas, Hooghly, Nadia, and Purba Bardhaman — concluded today. The trajectory through the day pointed toward a strong but somewhat lower turnout than Phase 1. By 1 PM, Phase 2 had recorded 61.11% overall, with Purba Bardhaman leading at 66.80%, Hooghly at 64.57%, Nadia at 61.41%, North 24 Parganas at 59.20%, Howrah at 60.68%, and Kolkata South — TMC’s home turf — at 57.73%. Wb The final Phase 2 figure is expected to settle between 88% and 90% — still historically high, but notably lower than Phase 1’s north Bengal and Jangalmahal surge.
That gap between phases is itself a data point. It suggests the extraordinary mobilisation energy was concentrated in Phase 1 territory — which is simultaneously BJP’s strongest geography and the SIR controversy’s sharpest flashpoint.
The question every analyst must answer before making a prediction is brutally simple: who were those extra voters in Phase 1, and why did they come?
The SIR: The Most Consequential Controversy of This Election
Between October 2025 and March 2026, the Election Commission of India deleted 9.1 million names from Bengal’s voter rolls — shrinking the electorate by nearly 12%. Over six million were categorised as deceased or absentee. The status of 2.7 million remained pending before tribunals when voting began. Approximately 65% of those undecided deletions were Muslim. Dalit Hindus — particularly from the Matua community, historically BJP’s most prized vote bank in Bengal — were also disproportionately affected in districts like Nadia and North 24 Parganas, where over 300,000 Matua voters were deleted from rolls in North 24 Parganas alone.

The BJP defended the exercise as the removal of bogus entries and undocumented migrants. The TMC called it deliberate disenfranchisement. Ground reports documented both genuine errors and genuine anxiety: Matua families in Bagdah and Thakurnagar discovering their names gone, CAA citizenship applications unanswered after two years of waiting, migrant labourers returning from Gujarat and Tamil Nadu specifically to verify they could still vote.
Murshidabad registered a final confirmed turnout of 93.67% — in a district where over 66% of voters are Muslim and the BJP is a marginal presence. Individual seats like Shamsherganj, Lalgola, and Bhagabangola exceeded 95% in Phase 1 live data. There is one straightforward interpretation of that number: it is a consolidation vote, and it flows in one direction.
But here is the counter-narrative that cannot be dismissed. The record turnout percentage is partly a function of the SIR itself — with nine million voters deleted from the rolls, even a similar absolute number of votes would produce a higher percentage due to the smaller denominator. MyNeta What if the deletions suppressed genuine residents who simply could not vote because their names were gone — and the high percentage reflects a truncated electorate voting at elevated rates, not a larger one mobilised by anger? The absolute vote count on May 4 will matter as much as the percentage.
Both readings of the same data are internally consistent. That is what makes this election genuinely uncertain.
Reading Each Region
North Bengal (54 seats, Phase 1) was always going to be BJP’s most competitive territory. The Rajbanshi belt in Cooch Behar, the tea garden tribal vote in Jalpaiguri and Alipurduar, and the Darjeeling hills — these are constituencies the BJP has cultivated for a decade. Cooch Behar’s 96.2% and Dakshin Dinajpur’s 95.44% are BJP-leaning districts voting at extraordinary rates. BJP is expected to win 22 to 30 seats here. But Malda — which recorded 94.79% — is a Muslim-majority and Congress-influenced district where that same high turnout likely reads very differently. North Bengal is a near-draw overall, but the energy is real on both sides.
Central Bengal (68 seats, Phase 1) — Murshidabad, Nadia, Birbhum, and the Bardhaman districts — is where this election’s true centre of gravity lies. Murshidabad at 93.67% points toward a near-complete TMC sweep. Birbhum at 94.51% is TMC territory with a complicated history of violence and cadre dominance. Nadia is the most complex sub-region: the Matua Hindus who gave BJP a meaningful foothold here in 2021 are now living the consequences of CAA delays and SIR deletions simultaneously. BJP’s ceiling in this 68-seat region is estimated at 18–20 seats. Their floor could be as low as 10. Congress, contesting seriously in Murshidabad under Adhir Ranjan Chowdhury, could pick up 4–8 seats — their best realistic chance of revival in the state.
Metro Bengal (108 seats, Phase 2) — South 24 Parganas, Howrah, Kolkata, Hooghly, and North 24 Parganas — is TMC’s structural fortress and the Phase 2 story. In the 2021 assembly elections, TMC secured a dominant victory in this belt, winning 123 of the 142 seats. Wikipedia BJP won zero seats in Howrah in 2021. South 24 Parganas is widely considered impregnable for any opposition. The notable detail in today’s Phase 2 data is that Kolkata South — Mamata Banerjee’s own Bhabanipur constituency — recorded a relatively lower early turnout of 57.73% by 1 PM compared to suburban districts. Whether that reflects urban voter apathy or simply a later voting pattern in the city will become clear on May 4. In the TMC scenario, this region delivers 80–90 seats. In the BJP scenario, it needs to deliver 50–55 — roughly double their 2021 Phase 2 performance.
Jangalmahal and the South-West (64 seats, Phase 1) — Purulia, Bankura, Jhargram, and the Medinipur districts — is where the prosperity deficit narrative is most acute. Ground reports document a voter who wanted peace in 2011, received it, and now wants economic delivery. Purba Medinipur at 92.75%, Bankura at 92.55%, and Purulia at 91.59% all recorded strong Phase 1 numbers. Suvendu Adhikari’s Purba Medinipur base is expected to deliver BJP a cluster of seats. The Sarna tribal identity movement in ST-dominated constituencies adds a quiet wildcard. BJP likely takes 18–24 seats here; TMC holds 33–40.
The Two Scenarios
This is not an election that ends in the middle. The structural dynamics of Bengal — the welfare state on one side, the identity and consolidation politics on the other — tend to produce wave outcomes rather than narrow margins. There are essentially two plausible results on May 4.
Scenario A — TMC fourth term (170–220 seats): TMC holds its metro fortress in Phase 2, limits Phase 1 losses to the mid-70s, and the SIR anger translates into consolidated minority and rural-poor turnout. The 93.67% Murshidabad number is the leading indicator. This scenario carries the higher probability, for one structural reason that opinion polls consistently underestimate: the woman receiving Lakshmir Bhandar payments every month, the family covered under Swasthya Sathi, the farmer getting Krishak Bandhu — these voters do not appear in telephone opinion surveys. They appear on polling day. In 2021, every exit poll projected 150–160 seats for TMC. The actual result was 215. The record turnout is partly a function of the SIR’s smaller denominator MyNeta — but the absolute numbers still represent millions of voters making a deliberate choice to show up.
Scenario B — BJP majority (148–200 seats): The record Phase 1 turnout represents genuine Hindu consolidation cutting across caste and class. Under this scenario, BJP sweeps north Bengal with 28–32 seats, converts Jangalmahal’s frustration into a near-complete sweep, and makes sufficient inroads in North 24 Parganas and Hooghly in Phase 2 to cross 148. The relatively lower Phase 2 early turnout in Kolkata South could, under this reading, reflect urban voter fatigue with TMC rather than TMC-leaning enthusiasm. For this path, BJP needs Hindu vote share to move from roughly 45% in 2021 to 58–60%, tribal ST vote to hit 55–60%, and critically, the Matua community to hold at 70%+ for BJP despite SIR deletions. Prime Minister Modi addressed a rally in Thakurnagar — the nerve centre of Matua politics — on April 26, personally reassuring the community of CAA citizenship processing. MyNeta Whether that last-minute intervention moved votes is unknowable until May 4.
What makes Scenario B impossible to dismiss entirely is one historical precedent. In the 2019 Lok Sabha election, BJP went from 2 Bengal seats to 18 in a single cycle — a swing that every analyst had called structurally impossible given TMC’s booth-level dominance. Bengal’s electorate demonstrated it is capable of dramatic, rapid realignment when the emotional and identity conditions are right. Nobody who lived through June 2019 in Bengal should be completely certain about anything on May 4.
The Four Alliances — Expected Outcomes
TMC+: 170–220 seats. The range is wide because the wave, if it comes, comes big in Bengal. The floor of 170 assumes BJP sweeps north Bengal, Jangalmahal turns significantly, RG Kar anger costs TMC metro seats, and the Matua vote partially returns to BJP — all simultaneously. Even under those conditions, TMC’s South Bengal fortress and Murshidabad sweep holds them above 170. The ceiling of 220 would be historic, but 2021’s 215 reminds us it is not without precedent.
BJP: 54–120 seats. The remainder range once other alliances are accounted for. In the TMC wave scenario, BJP finishes 67–80. In a tighter outcome, 95–105. In their own wave scenario, 148+. The ABP/CNN-News18 poll projects BJP at 124 — a figure questioned by analysts who note these polls systematically over-sample urban, English-accessible respondents who skew BJP. The 2021 polls made the same error, projecting BJP at 130–150 when the actual result was 77.
Congress: 3–10 seats. Entirely concentrated in Murshidabad and Malda. The floor of 3 reflects the very real risk that internal factional rivalry splits the Congress vote in seats they should win — a pattern with deep historical roots in Bengal Congress politics. The ceiling of 10 requires Adhir Ranjan’s personal hold on Baharampur to translate into a broader district sweep.
Left Front + ISF: 2–10 seats. The floor of 2 is essentially Bhangar — where ISF’s Naushad Siddiqui, the sitting MLA, is the closest thing to a safe bet in this alliance — plus one CPIM urban seat in South Kolkata. The ceiling of 10 requires ISF to win 3–4 of their 33 contested seats and CPIM to crack 5–6 urban constituencies where Mohammad Salim’s campaign had genuine momentum.
Three Seats That Will Tell You Everything
Before the full picture emerges, three specific constituencies will function as bellwethers — early signals that reveal which scenario is actually unfolding.
Shamsherganj, Murshidabad. This Muslim-majority seat recorded one of the highest individual turnouts in the entire state, exceeding 95% in Phase 1 live data. With over 75,000 voter names having been under SIR review in this constituency alone, it became the most visible symbol of the deletion controversy. Watch the margin. If TMC wins by 30,000 votes or more, the SIR backlash is real and Murshidabad is a sweep — Scenario A is confirmed. If the margin is compressed under 15,000, it means the deletions suppressed genuine voters rather than energising them, and Phase 1’s arithmetic shifts in BJP’s favour.
Bagda, North 24 Parganas. The Matua heartland made literal — BJP and TMC are both fielding candidates from the Thakurbari family, the religious dynasty at the centre of Matua politics in Bengal. It is the single seat where the fate of the CAA promise, the SIR controversy, and Hindu refugee identity politics are all concentrated into one result. A BJP win here means their Matua vote bank held despite everything. A TMC win means the community has genuinely turned — and BJP’s entire Phase 2 arithmetic collapses.
Bhangar, South 24 Parganas. ISF’s Naushad Siddiqui won this seat in 2021 as a first-time candidate in the heart of TMC’s most impregnable district. He is defending it again. If ISF holds Bhangar, the Left+ISF alliance has demonstrated it can survive in TMC territory. If TMC wins it back, it signals that minority vote has fully consolidated behind Mamata — which is paradoxically the strongest confirmation of Scenario A, since it means the SIR backlash theory holds in its most complete form.
These three seats will collectively answer the three biggest questions of this election: Did the SIR energise or suppress the minority vote? Did BJP hold its Bengali Hindu refugee base? And is there a viable secular third space outside the TMC-BJP binary? No television panel will tell you more in the first two hours of counting than the margins from Shamsherganj, Bagda, and Bhangar.
A Note on Urban Perception
One signal worth contextualising carefully is the strong anti-TMC mood visible in Kolkata’s educated, urban, upper-middle-class circles. That sentiment is real, well-founded, and grounded in genuine grievances — the RG Kar case, the recruitment scam, 15 years of governance fatigue. Within that demographic, the conviction that TMC is losing is near-universal.
But Kolkata city proper has 11 assembly seats out of 294. The voters expressing this sentiment most loudly — articulate, professionally mobile, socially connected — are the decisive constituency in perhaps 6 to 8 of those seats. They are not visible in the political conversation of Murshidabad’s villages, South 24 Parganas’ fishing communities, Bankura’s tribal hamlets, or Malda’s agricultural districts. Those voters are having a different election entirely.
In 2021, the drawing rooms and social media feeds of urban Kolkata were equally convinced of a BJP wave. Every major exit poll agreed. The actual result was TMC 215, BJP 77. The gap between urban perception and electoral reality was, in seat terms, nearly 140 seats. That gap exists not because urban Kolkatans are wrong about what they feel, but because the state’s demographic and geographic centre of gravity sits far outside the city’s boundaries.
27% of Bengal is Muslim. That single demographic — almost entirely invisible in the upper-middle-class Kolkata conversation — is the decisive or highly influential vote in roughly 80 constituencies. The woman in Basirhat, Contai, Ghatal, and Diamond Harbour receiving Lakshmir Bhandar payments does not appear in drawing room surveys. She appears on polling day. The street pulse of Kolkata is one data point. It is not a representative sample.
The Morning of May 4
Counting begins at 8 AM. The early leads from north Bengal and Jangalmahal will arrive first — BJP territory, where strong early leads are expected regardless of who ultimately wins. The real signal will come when Murshidabad starts reporting. Watch Shamsherganj’s margin before anything else.
If BJP leads 60+ Phase 1 seats by 10 AM, Scenario B is live. If TMC holds Phase 1 losses to 25–30 and Murshidabad comes in as expected, the trajectory points firmly toward Scenario A. The metro Bengal numbers arriving through mid-morning will be confirmatory, not decisive.
The full projection: Alliance Range Central Estimate
TMC+ 170–220 185
BJP 54–120 82
Congress 3–10 7
Left + ISF 2–10 6
Bengal has voted. The numbers will speak on May 4.
What is not uncertain is this: whichever side wins, it will not be close. Bengal does not do close. It does waves. The only question remaining is which direction this one broke — and three constituencies in Murshidabad, North 24 Parganas, and South 24 Parganas will answer that question before most of the country has finished its morning tea.
