In Tripura, the ruling Left Front's campaign strategy rests on one face: Chief Minister Manik Sarkar. For years, the four-time chief minister's clean image had been enough to see his party through. This time, Mr Sarkar's most ardent supporters concede he has a fight on his hands. The BJP has run a high-pitched campaign against the Left Front government to unseat Mr Sarkar whose coalition had won 50 out of the 60 seats in the 2013 assembly polls including 19 out of the 20 seats reserved for tribals.
