Did you know that there is a system in our constitution, as per Rule 49-O of the Conduct of Election Rules, 1961, that a person can go to the polling booth, confirm his identity, get his finger marked, and convey the presiding election officer that he / she doesn't want to vote anyone!
Yes, such a feature is available, but obviously these seemingly notorious leaders have never disclosed it. This is called '49-O'.
Why should you go and say 'I VOTE NOBODY'? ... Because, in a ward, if a candidate wins, say by 123 votes, and that particular ward has received '49-O' votes more than 123, then that polling will be cancelled and will have to be re-polled. Not only that, but the candidature of the contestants will be removed and they cannot contest the re-polling, since people had already expressed their decision on them.
This would bring fear into parties and hence look for genuine candidates for their parties for election. This would change the way, of our whole political system... it is seemingly surprising why the election commission has not revealed such a feature to the public.... Please spread this news to as many as you know... Seems to be a wonderful weapon against corrupt parties in India... show your power, expressing your desire not to vote for anybody, is even more powerful than voting... so don't miss your chance.
