Sources in 10, Janpath said although none of the three have not responded to the Congress president's wish, but the party strongly feels that these three men can play a major role in unsettling the poll equations and counter-pose a major threat to the ambition of the BJP and its prime ministerial candidate, Narendra Modi.
Both the Congress and BJP are trying to get Rajnikanth on board to make an impact in the southern state of Tamil Nadu where the actor has a massive following. Both the national parties have weak presence in the southern state and both think the superstar actor could help them make substantial gains there.
The BJP tried to bring Rajnikanth at a rally addressed by Modi last month and now the Congress is eyeing to get close to the man with a hope to make a comeback in a state which sends 39 members to the Lok Sabha.
The report said the Congress also asked Rajnikanth that he could form his own party and enter into an alliance with it, something Telugu superstar Chiranjeevi had done in the past.
The Congress has been also trying to win confidence of BS Yeddyurappa, a powerful politician from the neighbouring Karnataka who left the BJP and floated a new party before this year's assembly polls, which badly hurt the saffron party.
The Congress will try to get a hold over the Lingayat votebank by getting closer to Yeddyurappa while a section of BJP supporters is also keen to get him back into the party fold to make a turnaround in Karnataka where it lost power. Yeddyurappa is trying to make a comeback into the NDA but in politics, conclusion is a hard thing to draw.
The Congress is also trying to get closer to Bihar Chief Minister Nitish Kumar after the latter dumped the BJP and Congress's old ally Lalu Prasad was jailed in connection to the fodder scam. It looks mutually beneficial if Nitish Kumar joins hands with the Congress for after the divorce with the BJP, the task of Nitish Kumar to go alone and perform has become difficult.
The man has decided to join the Left Front and the JD(U) will also contest the assembly polls in Rajasthan and Chhattisgarh with Left parties and other so-called secular forces. But the Third Front is undoubtedly a strategic move for the Left, Samajwadi and JD(U), who will seek the Congress's support or back it as and when the situation demands.
