In 1982 BJP has only 2 seats in Parliament. One is Advani and the other is Mr. Janga Reddy from hanumakonda in Telangana. BJP was always getting between 15-20% votes in Telangana since 80's. But BJP betrayed the telangana people by not reinstating the promised telangana state. It has done so to lick chandrababus boots. Since then BJP vote share fallen to less than 2%. It has lost all its ideological base in Telangana. Had they formed Telangana state, Telangana would have been their first state to victory in South.
BTW, Telangana is the only region in india, which got freedom by Armed rebel. 5000 people martyered in the fight against Nizam and Rajakars.
