Superstar Rajnikanth may take a full-fledged plunge into politics two years after wrapping up what could be his last blockbuster. At least, that is what he appears to have told BJP president Nitin Gadkari. Gadkari was invited to Rajni's home here on Friday evening as a follow-up on the BJP chief's rescue act when the actor and his family were about to be mobbed at the Wankhede stadium after the World Cup final in Mumbai on April 2. Rajni let his mind known when he and Gadkari were chatting on his life, films and politics, particularly the Tamil Nadu poll scene, BJP sources said. The superstar was not impressed by the choices before the people of Tamil Nadu. He expects people to seek a third alternative in the years to come and he might not let them down then.
