Focusing on majority resentments is a lost cause. The majority is not grateful (and will not remain content with cultural bribery, at the end it is still jobs, jobs, jobs) and the minorities resent you back.
If you look at the recent track record of the parties of, for and by the majority natives such as BJP in India and the Repubs in the US, focusing on majority resentments can at best get you to regional dominance (North,West in India, South in US). Sure, you can veto all legislation in (US) Congress but then you are portrayed (justifiably) as the party of no (compromise). Jihads (against Obamacare for example) may excite passion but they will not be long lasting. Even if budgets have to be slashed people will prefer that the Dems do it, because they will be (a little more) kind to the 47%.
What is the incentive for a Christian in Kerala to vote for the BJP?
Similarly, Indians in the US will vote for Dems (85%?) because they do not identify with the “Judeo-Christian” heritage of the US. Even Jews do not vote for a party which seems to be more sympathetic to the Jewish (zionist) cause.
Finally the case of Muslims. I believe Muslims used to have a mild preference for the Repubs (GWB in 2000) which was poisoned by the anti-mosque politics (and “crusades” of GWB). They think (as Zachary has pointed out) that Obama will be less interested in bombing Iran etc. Following the budget analogy above, if ME states have to be bullied, people (american muslims) would prefer that Obama does it (in a responsible manner).
Minorities will only vote for BJP/Repubs if they feel threatened or if they have grievances against the competition. Thus Sikhs re-voted for Akali Dal/BJP in Punjab, even with the symbolic stain-washing exercise of appointing MMS as PM, they will never forgive/forget 1984 (justifiably). In Gujarat, Narendra Modi will be getting a fair share of Muslim votes which can be considered as protection tax (jizya). But is that really the BJP ideal? Beat up minorities so hard that they will vote for you out if fear? Also what happens when the dictator dies (inevitably)? IMO Shivraj Chouhan in MP is doing an admirable job and is plausible as PM material but NaMo is not.
Zachary never misses an opportunity to point out how Modi can be the next PM (and what that implies about the Indian ideal). The fact remains that the BJP simply cannot come to power without support from allies to the east and south. Bihar, Orissa, Andhra and even Assam were all aligned with the NDA at one point of time. Nitish Kumar has made it clear that he will veto NaMo as an NDA PM. At this point NaMo reflects Gujarati pride and even then there are defectors (e.g. Patels of Saurashtra under Keshubhai Patel). If NaMo ever plans to run for PM he will be (like Mitt Romney) an also-ran.
