After the death the Karunanidhi and Jayalalithaa - a power vacuum has consumed the state and the outcome has been a battleground for alliances for the 39 Lok Sabha seats with the national parties, the BJP and Congress joining the fray.

The BJP is eyeing the south to boost its numbers at the Centre after the setback in Hindi belt in December 2018 and the DMK is one of the very few allies with which the Congress has managed to form a tangible anti-BJP front. So who has the winning combination in Tamil Nadu?
