New Delhi, Jan. 21 -- Nitin Nabin, 45, a five-term legislator from Bihar took charge as the 12th national president of the Bharatiya Janata Party on Tuesday, marking the beginning of a generational shift in the party that was formed a month before he was born in May 1980. In his first address as party chief, Nabin had a message for the young. "Distance from politics is not a solution, active engagement is. But, politics is not a 100 metre race. It is a marathon which will test your stamina, not speed." The youngest president of the BJP to date, Nabin was handed over the election certificate by the returning officer K Laxman in the presence of Prime Minister Narendra Modi -- who described the new party president as a millennial and his boss -- and senior party leaders at the party headquarters amid loud cheering from the party cadre. He later assumed office in their presence. Nabin who has been a minister in the Bihar government and held various organisational positions, said his elevation as party chief is a "moment of resolve for him" and made a pointed reference to the upcoming elections in five states."Today, I am not just assuming a position. I am accepting the ideology, traditions, and the responsibility of a nationalist movement of this party," he said shortly after being declared the new party chief. Nabin who will lead the party as it heads into elections in five states, set the tone for the poll narrative, pointing out the challenges of a demographic change that is visible in the poll bound states of Tamil Nadu, Assam, West Bengal, Kerala and Puducherry. ". the demographics of these states are being widely discussed. The changing demographics are altering the situation there, and this presents a challenge for us. However, we are completely confident that the BJP workers, through their struggle and hard work, will lead the BJP to success in all five states," he said....
