AAP may not get absolute majority but its presence as 2nd largest party can also not be denied at least in the forthcomming elections especially when cong is most unlikely to regain its base. So, AAP can still play a constructive role in assembly in the larger interest of the society and consolidate its position. Hence, no reason to be hopeless since everything is not lost. AAP's overnight success perhaps needed such correction, by law of average, to make it more balanced and matured party.
As first preference, I would like to see AAP with absolute majority. Otherwise also, AAP is definitely preferable to Congress as main opposition because AAP has definitely proved a point or two if not all. more
