HOW has Rajnikant, one of the most apolitical of Tamil stars, become a political trump card overnight for the DMK-Moopanar Congress combine? Going by sheer numbers, the reach and influence of the superstar can be computed when you take into account that this time around there are three million new voters in Tamil Nadu in the 18-23 age group. Add to this the 20,000-odd fan clubs all over the state with a total of five lakh registered members and you have the committed Rajni votebank which is primarily youth power. But the Rajnikant phenomenon is not being driven on youth steam alone. A few months ago, not many people above 40 would consider the star their guru or his utterances pearls of wisdom. But Rajnikant has now been shaped into an anti-Jayalalitha symbol by the DMK and has become the number one vote-catcher in the state.
