"...Regaining Karnataka is very important for the party. We will do whatever is required to regain the lost ground in the state," Rao told reporters here.
Rao said the mandate given by the people in the Lok Sabha elections was to see BJP as a strong opposition in Karnataka and hence, it would adopt an aggressive stance to expose the Congress government's shortcomings.
The party would galvanise people outside and inside the assembly and "will give sleepless night to the government," he said.
He also said that keeping in mind the massive support given by the people in recently concluded polls in Maharashtra and Haryana, the party hopes and is confident that the trend would continue in the Jammu and Kashmir and Jharkhand polls.
Keeping in view the growing popularity of BJP across the country, Rao said the party has decided to launch membership drive in southern and eastern parts of the country.
