It is an unarguable fact that Congress is in a better position in Telangana after TRS even though it is miles away from coming back to power. But then, BJP do not want Congress to register even a slight improvement. But BJP may provide it an outside chance.
BJP is distancing itself from TDP (TS) and is already speaking of no alliance with the party in the upcoming elections. On the other side, TDP (TS) Working President, Revanth Reddy has indicated that the party will even consider an alliance with Congress if needed.
That will only mean that Congress will have an added advantage. BJP can at most severe ties with TDP (TS) but can not force the yellow party not to go alone in Telangana. So, BJP may be giving a chance of revival to Congress.
