Yeah Rajeev! You have said the right thing. It doesn't work out in India with this kind of set up.
You can fight an election even after having 3 childern. This is no bar for contesting.
As far as criminal background is concerned, the more criminal background you have the more laurels and sympathy you get from the party. This statement could offend you but this is the fact. Pls do not mind.
Election commission never reject candidates from a succesful party. Soughting affidavits, undertakings are only for public consumption sake. It doesn't have any useful relevance as of now.
Therfore, do not get disheartened and file your nomination as and when the time comes and try to be like the other candidates otherwise you would be a kind of gentle fish out of pond and it will not serve any purpose.
Be like a Roman while in Rome.
