Mr Modi is indeed suave, far smarter than the other diaspora darling, Chandrababu Naidu of Andhra Pradesh. Mr Naidu, to be fair, had a far worse hand than Mr Modi, a poor state fighting deep-rooted Maoist insurgency as opposed to Mr Modi's generally prosperous and enterprising Gujrat. If there was to be any challenge to Mr Modi's power from its minority Muslim community (rich as they are in certain areas), he fired a decisive warning shot at them through the riots early in his career and has managed to put them in place. He has also effectively maintained a 'professional' image, clean, efficient, ruthless, something that upper class diaspora Indians love to see. They have started dreaming of the day Mr Modi becomes the Prime Minister of India, and they can start winning back the position they, and their parents, 'deserve' in the society.
However, as India has become economically attractive, a Brahminic Backlash may be in the making. Several opportunities may open for the exiled elite at the same time: The ability to participate in economic life, which has already happened, may now be supplemented with greater powers with media, education and eventually politics, with the liberalization of different sectors and eventual expansion of diaspora rights. This is indeed no justification for protectionism - India must not assume that its democracy is fragile - but it is important to solidify the democratic institutions in the country, which will help to co-opt both the disenfranchised in India as well as the non-resident brahmins. If this isn't done, the inevitable economic logic of liberalization will eventually unleash the power of non-resident communities into Indian political landscape. If democracy failed to deliver, it will surely be transformed.
