Justice Markandey Katju writes: BJP gets its support not from its performance but from its Hindu identity. As the elections approach, the agitations against the Gyanvapi mosque in Varanasi and the Shahi Masjid in Mathura (as well as other places) will be stepped up, and communal riots break out in many parts, to create a communal frenzy in India, which will ensure BJP victory in the polls.
