Since it is conventional wisdom that polls conducted by Indian organizations are bogus (americans are saying so, one TV channel is also up with a sting operation) the next logical step is for the US organizations themselves to roll up their sleeves and step up to the plate and clear up all the confusion (+/- 3.8% is pretty credible). This in turn shines a spotlight on how much the americans are prepared to invest to make sure that they are well aligned with the coalition that will presumably rule India for next five years.
The survey has been conducted in all corners of India (Kerala excluded) and across all categories/divisions (gender, age, education, income, rural vs urban) BJP bests Congress by a huge margin.
At the lower end of the scale are the following: low income group (+37), 50+ age group (+37), women (+38), urban (+39). At the higher end we have the following: college degree (+52), middle income group (+49), men (+48) and (high) school certificate (+48).
What conclusions can we (imperfectly) draw from this? The Indian muslim population is less wealthy and more urbanized, this may help explain the low points. The middle class, well educated men form the backbone of the IH community so the high points are also not a surprise. Thankfully women appear to be (just a bit more) sensible as compared to men and aged people may recall the good old days of Nehru/Gandhi. Since the old generation will be fading away it appears that the hope for a secular India lies with her women. Stree Shakti is the best, it seems (as it was in the Vedic past when goddess Durga rode into battle against Mahisasura).
As far as regional differences are concerned: North (+74), followed by South (+42), West (+33) and East (+27). The southern anomaly is the most interesting data point of all. Explanations are (1) poll is crap, (2) shudras are relaxed about Sir-ji (why not? he is one of them, no?), (3) Kerala was not counted, (4) a bit of all of the above. If true this suggests that the southern leader-ess and others who may be thinking of jumping into bed with BJP will not be suffering any serious backlash if they decide to jump.
All in all Pew appears to confirm that the middle-caste, sons of the soil are ready to take back the power invested with mixed blood (also foreign blood) monarchs who have (mis)ruled India almost without break for so many centuries past. The shudra king of a shudra nation will not be stopped in his tracks by a bunch of liberal, pseudo-secular, activists. This is how democracy works, folks.
