With the 2026 West Bengal Assembly elections approaching, multiple opinion polls and trend analyses indicate a closely fought contest between the ruling Trinamool Congress (TMC) and the Bharatiya Janata Party (BJP), with district-level dynamics expected to play a decisive role across the state’s 294 constituencies.

Poll aggregations compiled from surveys conducted by agencies such as CVoter, Axis My India, and other national pollsters suggest that the TMC continues to hold a marginal lead statewide.

Most projections place the Mamata Banerjee-led party in the range of 140 to 190 seats, while the BJP is projected to secure between 100 and 150 seats, pointing to a competitive bipolar contest.

According to a Moneycontrol report citing recent opinion polls, the TMC retains an edge due to its welfare schemes and strong grassroots network. Still, the BJP has significantly improved its position compared to earlier cycles, especially in regions where it performed well in 2021.

Similarly, aggregated election data referenced by CVoter’s 2026 West Bengal Assembly election page shows a tightening vote share gap between the two principal parties, reinforcing the perception of a closer-than-expected contest.

Regional divide shapes district-level trends

District-wise trends emerging from these surveys highlight a clear geographical divide in voter preferences. South Bengal districts, including Kolkata, South 24 Parganas, Birbhum, and Nadia, continue to favour the TMC, largely due to the party’s entrenched organisational strength and beneficiary outreach through flagship welfare schemes.

In contrast, North Bengal districts such as Alipurduar, Cooch Behar, and Jalpaiguri are witnessing stronger BJP momentum.

According to a OneIndia analysis of district-wise voting patterns and emerging trends, these regions have shown consistent support for the BJP in recent elections, a trend that appears to be continuing in current opinion polls.

  1. Western districts like Purulia, Bankura, and Jhargram remain battlegrounds, with both the TMC and the BJP locked in close contests. Pollsters suggest that even minor swings in voter turnout or alliance arithmetic could determine outcomes in these constituencies.
  2. Meanwhile, districts such as Murshidabad and Malda present a more fragmented picture. These areas, traditionally strongholds of the Congress and Left Front, continue to show residual influence of these parties.
  3. However, most surveys indicate that their overall impact may be limited to a handful of seats, unless tactical voting alters outcomes.

Seat-level trends and limitations of opinion polls

While district-wise projections offer valuable insights, it is important to underline that no credible polling agency has released a verified, constituency-level list covering all 294 seats.

Opinion polls typically provide aggregate seat ranges and vote share estimates rather than definitive seat-by-seat winners.

However, broad classifications based on poll trends suggest the following pattern across constituencies:

  • TMC leading in a majority of seats across South Bengal and urban clusters
  • BJP leading in several North Bengal and western belt constituencies
  • Dozens of seats in districts like Hooghly, Howrah, and North 24 Parganas marked as “too close to call”
  • Limited but notable presence of Congress-Left candidates in select minority-dominated constituencies

These trends are derived from aggregated polling data and district-level analyses reported by media platforms and election trackers, rather than individual constituency forecasts.

Leadership factor and voter sentiment

Chief Minister Mamata Banerjee remains the central face of the TMC campaign, with surveys consistently showing her as the preferred chief ministerial candidate. Her government’s welfare schemes, ranging from direct cash transfers to social support programmes, continue to influence voter sentiment, particularly among women and rural voters.

On the other hand, the BJP is banking on anti-incumbency, organisational expansion, and its performance in the 2021 elections, where it emerged as the principal opposition.

Pollsters note that the BJP’s ability to consolidate votes in North Bengal and make inroads into South Bengal will be crucial to its prospects.

A high-stakes finish ahead

With polling expected later this month, the electoral battle for West Bengal’s 294 seats appears to be heading toward a high-stakes finish.

While the TMC holds a statistical advantage in most opinion polls, the narrowing margins suggest that the outcome could hinge on swing districts and closely contested seats.

As past elections in the state have shown, Bengal’s political landscape can shift rapidly, making ground-level mobilisation and last-mile campaigning critical in determining who ultimately forms the next government.
