As a six-time member of Parliament, Kumar had climbed the political ladder steadily from being an RSS worker to be the Union minister in his thirties.
Kumar had been in the inner circle of the central leadership of the BJP -- be it during the heydays of Atal Bihari Vajpayee or L K Advani and now Narendra Modi.
He joined the BJP in 1987 and never looked back, as he held posts of state secretary, state president of the Yuva Morcha, general secretary and national secretary.
Along with state BJP chief Yeddyurappa, Kumar is among a few party leaders who can be credited for the growth of BJP in Karnataka, as they built the party and bringing it to power in 2008, making it the first saffron party government in the South..
Kumar first got elected to Lok Sabha in 1996 from Bangalore South, the constituency, which remained his bastion till his passing away.
