The fact and moral of the story is: -----------------------------------
All these people are desperatly trying to preserve/prevent and gain more attention of the aam aadmi. Its a kind of investment, that they will reap at the time of elections.
MNS will reap the benefits by attracting marathi votes.
SP will reap benefits by attracting Hindi-Votes.
Other parties want votes from both the sections as well as people from other linguistic origins. So they are waiting and watching for the right time.
After all, "purn 5 varshancha prashna aahe", aata he sagde zhol nahi kela tar hey sarva-samanya janatela kasa kaldnar, konala vote dyacha/takaycha.
