- On and off, parties have pointed to Rajinikanth's Marathi origins
- Kamal Haasan launched his political party in February
- Rajinikanth said he'll launch a party and contest in Tamil Nadu polls
He said the important point in any debate would be "how useful would one man be as against another man to help serve Tamil Nadu better".
"That's what you should debate instead of this parochial differences," Mr Haasan, 63, said as he undertook an unusual 300 km train journey from Chennai to Tiruchirapalli that is at the centre of the delta region dependent on Cauvery water. Mr Haasan is to address a public meeting tomorrow.
Of and on, leaders of the state's ruling and opposition parties have pointed to Rajinikanth's origins to question if people would accept him as a leader. Rajinikanth, 67, was born Shivaji Rao Gaekwad to a Maharashtrian couple living in Bangalore. His father was a police constable.
The two superstars are seen to be aspiring to fill a leadership vacuum in Tamil Nadu politics following former chief minister J Jayalalithaa's death in December 2016 and with DMK leader M Karunanidhi politically inactive because of poor health.
Mr Hassan told NDTV that what was important that people who come forward to serve the people "have the quality, qualification to do what they want to do".
"Gandhiji has come to Chennai 49 times in his life. And we accepted him as what he was. We did not think of him as a Gujarati. We thought of him as Father of the Nation. When we can celebrate those kind of relationships, anybody is welcome," said Mr Haasan, who launched his political party Makkal Needhi Maiam in February, promising an end to corruption, education for all and jobs for the youth.
In December, Rajinikanth had announced he would launch a party and contest all 234 assembly constituencies in Tamil Nadu in the next assembly elections due in 2021.
