Greater Chennai, northern T.N. may shape poll results

As Tamil Nadu braces for the results of its assembly polls, the two Dravidian majors — the DMK and the AIADMK — are keeping their fingers crossed to see whose votes the debutant Tamilaga Vettri Kazhagam (TVK) eats into more. The entry of actor C. Joseph Vijay’s party is expected to throw up surprises.
