These three candidates, with the DMK's current strength in the assembly, would be having comfortable entry to the upper house of the Parliament.

Vasan's campaign for the upper house has come at a crucial time when the senior leaders of ADMK have been stressing the party's chiefs to keep its candidates on the fray for the three Rajya Sabha seats.

With the current numbers of the MLAs in the assembly, the ADMK and DMK party can easily elect three MPs each without any election.
