The churning in the politics of soc-ial eng-ineering in Uttar Pradesh underlines the puzzle of caste coalition for electoral gains. The exodus of some infl-uential non-Yadav OBC ministers and MLAs from the visibly stable and confident BJP to the Sama-jwadi Party (SP) highlights the complexities associated with politics of ‘social justice’. With three consecutive electoral successes since 2014, the BJP claimed to have blunted Mandal politics and outsmarted other parties through its nuanced caste management. Its caste management worked on twin tracks: while the party’s grandstanding has been portrayed through ‘caste neutrality’ (sabka saath, sabka vikash), it gradually and wis-ely shaped the caste coalition and tried to checkmate the SP and BSP through deft social eng-i-neering. While the core of right-wing populism is grounded on religious nationalism and majoritarian politics—with the spectacle of ostentatious temple construction, grandeur of religious expansionism and minority exclusion—it made determined efforts to include fragmented caste groupings within its fold.
