I don't understand why this is being down voted. The op is backing his argument with a link to national news paper and he is getting down voted. This post getting down voted is the proof of educated people still having caste feelings within them. Thanks to the Indian Constitution, without it most of population in India would never had education.
I am not sure what your agenda is, but your response is disingenuous. You have taken a specific and rare incident which was reported for its "shock value" (it is quite easy in India to publish a story with an agenda) and have presented it in a manner which implies it is some sort of a norm.
While there certainly is corruption, given the size and scale of elections in India, it is laudable that things are conducted in a proper manner for the large part.
