After winning Bihar, the Bharatiya Janata Party (BJP) has shifted attention to poll-bound West Bengal, arguably the biggest prize that the saffron party has long been eyeing. Bengal matters to the BJP because it is the only eastern state where it is yet to make electoral gains, except in 2019 Lok Sabha polls. The state was a Left bastion until Mamata Banerjee's Trinamool Congress came to power in 2011. The BJP won just three assembly seats in 2016. A victory in Bengal, where Home Minister Amit Shah and party president JP Nadda are leading the campaign, would symbolically reinforce the party's national status across geographies, including eastern India, allowing it to implement its political agenda.
