Prime Minister Narendra Modi will kickstart BJP's poll campaign in the Northeast from Assam's Silchar, its oldest bastion in the region, on Friday. He will also inaugurate a dozen projects in Manipur, and address a public rally. The 25 Lok Sabha seats in the Northeastern region are key to the BJP's political prospects in the upcoming parliamentary polls. However, resentment may be building in Silchar. A majority of the people in this region -- the hub of Assam's Barak Valley -- are Bengali-speaking people, and a number of Bengali Hindus who voted for the BJP in the last elections were left out of the National Register of Citizens draft.
