Swami asks what “strategic” use non-voting could be put to.
Why, that’s simple. Suppose that you are a hardcore BJP supporter. I mean, so hardcore that building a Ram Temple at Ayodhya is the only issue you are concerned with and is your life’s mission. Suppose further that the BJP (not just NDA) has a comfortable majority in the Lok Sabha and cannot give the compulsions of coalition politics as an excuse anymore. And yet the BJP isn’t bothering to build a temple in Ayodhya, because it has other things to do, like building a shining India and making money for its own ministers.
So what do you do? You can’t vote for the Congress because the Congress isn’t going to build a temple for you either. You can’t vote for an even more extreme right-wing party, because either it doesn’t exist or because it has no serious chance of capturing power at the Centre. Your only choice is to stay at home and hope that the BJP gets a message that it can’t take you for granted.
