On February 24 this year, weeks before the dates of the general elections were announced, Prime Minister Narendra Modi washed the feet of five sanitation workers in a symbolic gesture aimed at countering opposition charges over the ruling party’s alleged bias against lower castes. Come election time and the discourse, predictably, is back to the country’s unwritten election theme, ‘Indians do not cast their vote, but vote their caste’. An ongoing spat between BSP chief Mayawati and Modi over the PM's OBC status has only deepened the caste fault lines.
