The BJP Coalition has the saffronista component but also, and far more importannt, IMO, includes what was in the 60's and 70's the Swatantra Party; a Pro-business and Pro-US party. Jaswant Singh, India's Foreign Minister comes out of this business/pro-US wing.
Does "saffronista" refer to the Hindu movement? That has been the one thing about the BJP that seems troubling to me. It seems to be portrayed as somewhat of a pro-Hindu, anti-any-other-religion party. I don't know how accurate that is, but I think that would be a bad thing in a country that is fighting separatist movements.
