Opinion | Fence-Sitter Exit Polls: Why Calling West Bengal Elections 2026 Is So Tough

West Bengal elections 2026 has Three Great Immeasurables. These grey areas of electoral mathematics have thrown calculations into chaos and predictions towards a dangerous precipice. As a result, we find most exit polls have played safe by forecasting a photo-finish, while giving the BJP a slight edge over the TMC.

Matrize, P-Marg, and Chanakya Strategy have predicted a very close result, tilting slightly towards the BJP.

While People’s Pulse shows an emphatic TMC victory, Praja Poll and Poll Diary have stuck their neck out for a clear BJP win.

Bigger pollsters like C-Voter and Axis My India did not even hazard a guess on West Bengal.

The hesitation to call the election is understandable. The election is proving to be one of the most unpredictable

in recent history. While conventional wisdom still gives TMC an edge, three major “grey zones” have made accurate forecasting extremely difficult. These factors—voter list revisions and their effect of “chhappa” or proxy vote, a possible hidden Hindu surge, and the silent or “chuppi” vote—have created layers of uncertainty that most pollsters and analysts are struggling to quantify.

First, it is impossible to ascertain what per cent of SIR deletions accounted for TMC proxy votes in the past. Revision of electoral rolls led to the deletion of nearly 92 lakh names across West Bengal.

This is an unprecedented churn. Independent estimates and reports from election observers suggest that 35-45 per cent of these deletions were likely proxy or bogus voters. These had solely benefited the TMC.

In several border and Muslim-majority districts, the number of deleted entries was disproportionately high. If even 40 per cent of the deleted nearly 1 crore were proxy votes that earlier inflated TMC’s margins, it effectively removed 40 lakh phantom votes from the system.

This directly weakens the TMC in several tight seats where its wins depended on inflated turnout. This one factor has made old election data far less reliable.

Second is the mystery of the record nearly 92.9 per cent turnout in the two phases. This is not normal. Who were those lakhs of extra voters?

One theory is that while Muslims always come out in large numbers to vote, this time there was a quiet Hindu surge across constituencies. In Hindu-majority and mixed constituencies, turnout has jumped 8-12 percentage points compared to 2021. This swell is most visible in semi-urban and rural seats in Bardhaman, Birbhum, Bankura, and parts of north Bengal.

The BJP and its allies are confident that this increased Hindu participation—driven by anti-incumbency, infiltration concerns, and Ram Navami mobilisation—will translate into seat gains. However, one can never be sure that a sizeable chunk did not vote for the TMC.

Third, the silent vote. This is perhaps the largest and most mysterious grey zone.

West Bengal has seen unceasing political violence for decades. NCRB data and independent reports show the state has consistently ranked among the top two in political murders and crimes against women under the TMC.

In such an atmosphere, millions of voters, especially in rural and semi-urban areas, are refusing to reveal their choice to surveyors and journalists. Many pre-poll surveys have shown unusually high “undecided” or “no response” rates (often 18–25 per cent).

Who will get this “silent vote”?

While it is right to presume that it may go disproportionately to the BJP, no one can be certain about the numbers. Just 12-15 per cent silent vote could swing 40-60 seats, given previous victory margins. But it is hard to capture this in an opinion or exit poll.

The combination of these three has created a highly opaque and uneasy electoral environment. Traditional polling methods are not enough to mathematically analyse this accurately.

The 2026 West Bengal election remains wide open. Till May 4 afternoon.
