I know there are about 100 million answers for this question. Why 100 million? Because I think that as of now these many are the number of citizens in India, who actually thinks about candidate for Prime Minister's post, before casting their vote for the LokSabha election. There are about 670 million voters in India. In majority of the general elections the voting percentage was around 60%. So the actual number of people who are voting comes down to approximately 400 million. My guess is out of this 400 millions, majority (approximately 75%) of the voting is done on the basis of caste, creed, regional and religious lines. It leaves us with 25% or 100 million of voters, who actually vote for keeping country's development and its long term needs in mind. These voters vote for different parties as per their preferences.
