- Amit Shah led data-driven, well-planned BJP campaign in Bengal
- Anti-incumbency against Mamata Banerjee central to BJP’s strategy
- BJP won 206 seats, ending Trinamool Congress’s 15-year rule
Following the BJP’s sweeping victory in West Bengal, Home Minister Amit Shah is being credited with orchestrating a highly structured, data-driven campaign, with party leaders highlighting early planning and deep grassroots engagement as decisive factors behind the landmark win.
According to BJP sources, Amit Shah began preparations well before the Bihar Assembly elections concluded in November last year, holding a series of strategy meetings in Delhi. By September 2025, the BJP had appointed Bhupender Yadav as election in-charge and Biplab Kumar Deb as co-incharge, tasking them with strengthening organisational coordination and expanding the party’s footprint across West Bengal.
A defining feature of the campaign was its granular, data-led seat classification model. Constituencies were divided into five categories, from strongholds to weak zones, based on winnability and organisational strength. Party insiders say this allowed for precise allocation of resources, sharper messaging and booth-level micro-management.
Over time, several constituencies initially seen as weak moved into stronger categories due to focused campaigning.
DATA-DRIVEN SEAT CLASSIFICATION
A key feature of the campaign was a granular classification of constituencies into five categories—A to E—based on electoral strength and winnability.
A Category: Stronghold seats considered near-certain wins
B Category: Favourable but requiring sustained effort
C Category: Highly competitive constituencies
D Category: Challenging seats needing intensive groundwork
E Category: Weak zones with low initial winning probability
FOCUS ON ANTI-INCUMBENCY NARRATIVE
Central to the BJP’s strategy was amplifying what it viewed as growing anti-incumbency against Chief Minister Mamata Banerjee and the Trinamool Congress. Amit Shah is said to have repeatedly emphasised aggressive outreach and sustained pressure in key constituencies.
One of the most high-profile contests was Bhabanipur, long associated with Mamata Banerjee, where BJP leaders claim strategic planning played a crucial role in delivering a breakthrough result. BJP leader Suvendu Adhikari defeated Mamata Banerjee, once his former party boss, in Bhabanipur, with a margin of over 15,000 votes.
EXTENSIVE CAMPAIGNING ACROSS BENGAL
Amit Shah’s on-ground campaign was among the most extensive by any national leader. He conducted around 40 programmes, covered 39 of the state’s 43 organisational districts, and reached 57 Assembly constituencies.
His campaign included 29 public rallies and 11 roadshows, alongside cultural outreach visits such as offering prayers at Gangasagar and the Kapil Muni Ashram, moves seen as aimed at connecting with local sentiments.
BOOTH-LEVEL MONITORING AND WAR ROOM STRATEGY
Sources indicate that Amit Shah maintained close oversight throughout the campaign. He chaired late-night review meetings with organisational leaders and reportedly examined seat-level feedback in detail. On polling days, he monitored developments from the BJP’s central war room, taking real-time updates from across constituencies.
Importantly, BJP insiders say the party avoided repeating its 2021 strategy of heavily relying on defectors from the TMC. Instead, this time the campaign focused on local leadership and region-specific issues such as women’s safety, unemployment, industrial decline and political intimidation.
CONFIDENCE IN ELECTORAL GAINS
Ahead of voting, BJP leaders expressed confidence about strong performances in districts like Jhargram, Purulia, Paschim Medinipur, Jalpaiguri and Darjeeling. Party estimates suggested a potential surge in vote share, with leaders claiming that extensive groundwork could translate into significant gains.
The BJP won 206 of 293 seats, dethroning the TMC after 15 years, and is set to form the government for the first time. The Mamata Banerjee-led party managed only 80 seats this time.
Within BJP circles, Amit Shah’s campaign is being projected as a model of high-intensity, data-backed election management, one that the party believes could shape its future electoral playbook in other states.
