Himanta Biswa Sarma, the BJP's main strategist in the northeast, says the party has assessed a three on three score as votes are counted in Tripura, Meghalaya and Nagaland today. "If we win Tripura and if we can regain Nagaland, have a government in Meghalaya, then our expansion in Northeast will be complete, barring Mizoram. Today will be a big day," Himanta Biswa Sarma told NDTV hours before counting.
