TRIPURA Chief Minister and CPI(M) Polit Bureau member Manik Sarkar addressed five huge rallies in Lower Assam on April 3 and 4 in support of party candidates from Bijni, Abhayapuri North, Sorbhog, Nalbari and Rangia Assembly constituencies. While top leaders of bourgeoisie parties such as BJP and Congress were travelling to places in helicopters to address rallies, Sarkar, despite being a Chief Minister, went for election campaign by travelling in trains which found some space in otherwise anti-Left electronic media.
