The weekend starting on Saturday July 8 will see hundreds of migrant laborers leave the city of Kolkata to cast their votes in the rural polls. They include riskhaw pullers, domestic helpers, construction workers, vegetable vendors, guards at residential and other buildings, electricians, plumbers and a host of others from the lower-income-group workforce who migrated to the city for livelihoods but whose names are still registered on the voting lists at their respective villages.
