In the village of Makhra in West Bengal's Birbhum district, Anjana bibi breaks down. Her brother Taushiq, 17 years old, was shot and killed, she told NDTV, in a raid by a Trinamool Congress mob on October 27, which was sparked by a dramatic shift in political loyalties. Makhra is a village almost entirely of Muslims, loyal to the Trinamool. But three weeks ago, like several villages in this Muslim belt, it made a surprise switch over to the BJP.
