The defining moment of the campaign for the 2014 Lok Sabha elections in Assam, many agree, came at a rally addressed by then prime ministerial candidate Narendra Modi. After May 16, he thundered, all Bangladeshis will be sent back “bag and baggage”. May 16 was the day when votes were counted and Modi’s BJP began its march into Assam, winning seven of the state’s 14 parliamentary seats. Exactly two years to the month, the BJP overran the Congress’s 15-year-old citadel in Assam, storming to power in the state for the first time. Throughout the weeks-long campaign, the BJP’s trump card, again, was the promise to deport all “illegal Bangladeshis”, the biggest and most divisive of all issues in Assam for decades.
