TDP has been waiting with a lot of patience that BJP will one day or the other restore its alliance that the TDP had severed in 2018, so that it can hope for some good support to win in AP assembly elections. TDP wants Jana Sena, BJP is already with Jana Sena but BJP doesn't want TDP.
Chandrababu Naidu is reportedly becoming restless that with weeks and months passing by, there's still no proper response from BJP. According to grapevine, Babu is not averse to go with Congress too, in case there's any chance of the party coming to power in Delhi.
Moreover, AP Congress chief has also not ruled out any alliance with others. Babu went along with Congress during Telangana elections in 2018. Now he is waiting desperately for BJP and is hoping that Congress becomes strong soon so that BJP will realize Naidu's significance. It's like a cat and mouse game.
