Why Posani Targets Only Jeevitha?

Posani Krishan Murali aka Mental Krishna has raised on Rajasekhar-Jeevitha couple when they expressed their views on Chiranjeevi. But the same Posani is not firing Roja or any other person who is lashing out Chiru. Why Posani is so focused on Jeevitha-Rajasekhar couple?
 
It is said by inside sources that Posani Krishna Murali has degraded to big extent that he can talk any nonsense before media camera if he is left like that. Hence Rajasekhar asked Congress groups to keep Posani shut his mouth if he needs to come to media again. That is the reason, Rajasekhar didn't hit any news channel after Posani's episode.
 
Now if Congress warns Posani and the latter fears for the same, Dr Rajasekhar-Jeevitha may again hit media and continue their verbal war against Chiranjeevi and PRP.
