The Special Intensive Revision of rolls has consumed our lives whole. In case you are lucky enough to have made it to the voter lists, you must surely be outraged at the way in which the process has been conducted. In case those news updates have slipped you, you must have seen how the protests against the SIR were brutally quelled. You must have read – aghast – reports of Muslim voters being targeted across the country through Form 7s which are meant for deletions. You must have read of or seen videos of how two of the Election Commissioners disagreed formally with the Chief Election Commissioner on several decisions on the SIR taken unilaterally by him. You must have wondered if you will be able to vote the next time there is an election. You must have also wondered what the use of an election was if the process of building the voter rolls is so fraught and so blatantly unfair.And then you must have resigned yourself to going about life again. Because what can you do? The SIR is complicated as it is, but its wrongdoings are even more complicated. To follow the news breaks, you need a compendium which is roughly the size of a tome. Nowhere is this complication more evident than in the state of Bengal, where within a period of five months, 90 lakh of the erstwhile electorate was erased, an election was held with whatever remained of the electorate, and a new government – incidentally of the Bharatiya Janata Party – was put to power.What exactly happened in Bengal? What do we know and what do we not? To help us all understand, data analyst and journalist Aparna Bhattacharya unfurls the SIR process to The Wire’s news editor Soumashree Sarkar.The video has been edited by Mohsin Arif.Aparna’s work on the SIR and Bengal’s political climate can be found here.Follow The Wire’s nationwide SIR coverage here.
