It is TRS in Telangana and TDP in Andhra Pradesh, that was heard big in 2014 elections and no other party could not make any impact among the public.
If not with the public, due to Jagan’s party, there was a tight split in the vote bank of Congress, which could not even get deposits in Andhra Pradesh. So in the present situation, Congress needs a boost to move forward in AP and that can be happened with the support of YSRCP.
On the other hand, even Jagan’s party is completely out of Telangana. So to progress in TRS leading state, even YSRCP needs a push up from Congress, which is the second leading in the state. Speculating this, Digvijaya Singh, in his recent visit to Tirupati, met Jagan secretely in the airport. "AICC is making trials to reunite YSRCP with Congress", says the sources.
