Tamil Nadu Assembly Election: EPS is hoping to lead the AIADMK to a third term (File) Chennai: Ten years of anti-incumbency, the absence of a larger-than-life leader and a fight for control of the party (from within and outside) has put the AIADMK and Tamil Nadu Chief Minister Edappadi K Palaniswami, or EPS, in a tight position, from which he has to buck the odds to emerge a winner. So the ruling party and its ally, the BJP, have decided to do what always works well - disappointingly so - in Indian elections - play the caste card to influence voters.
