It is a rather bizarre setting, but DMK president and Tamil Nadu chief minister M.K. Stalin appears unfazed as he rages against the Centre while campaigning via videoconference for the urban local body elections in Kanyakumari district.

But that’s nothing unusual in the Dravidian politics of Tamil Nadu.
