He was elected to the Assembly from the Dharmashala constituency four times in succession since 1990. Said to be Naveen's political advisor after the exit of former Rajya Sabha MP Pyari Mohan Mohapatra in 2012, Das had inched closer to the CM during the 2014 elections earning the resentment of several of his party colleagues. After the CAG in his audit report of allotment of houses and plots under Bhubaneswar Development Authority’s discretionary quota accused Das and his family members of cornering plots and houses, the tide turned against him.
