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.

Here is what Karan Thapar recently said about Modi in Hindustan Times article ...

If I’m right, the middle ground is shrinking, even disappearing. The emergence of a dominant idea on the saffron front and, in response, the creation of an equal but counterveiling force on the other will squeeze out everything else. The more Moditva grows, the more its opposite has to be strengthened. Increasingly the choice will be one or the other. We will have to take sides.

Where does this leave the regional parties and the Left? They may retain their identity, even their present base, but they will have to line-up behind Modi or Sonia, in the saffron camp or the liberal/secular one. They may even have to submerge themselves within the broad appeal of the camp they belong to.
