The Congress has been watching the movie Kal Aaj aur Kal (Yesterday Today and Tomorrow) for decades…

1960: Kal (Motilal) Aaj (Jawaharlal) aur Kal (Indira).
1980: Kal (Jawaharlal) Aaj (Indira) aur Kal (Rajiv).
2010: Kal (Rajiv) Aaj (Sonia) aur Kal (Pappu).

Right now they are hoping that Sonia will retire and Pappu will take over so that they can dream…
Kal (Sonia) Aaj (Pappu) aur Kal (Priyanka).
