Traffic Ramaswamy may not make any significant impact on the voting, but he wants to make a point.
"They are responsible for the 2G spectrum scam. I am going to expose it," he says.

Karunanidhi has won nine times from the DMK's bastion, Chennai. This is the first time since 1962 that he is not contesting the elections from there. Analysts say his homecoming to Tiruvarur was perhaps due to the worry that spectrum scam could dent its urban vote bank.
But with Traffic Ramaswamy preparing to highlight the issue of corruption, the 2G shadow clearly refuses to disappear.
