Delhi, as is repeatedly pointed out by political observers, has a huge chunk of Purvanchali voters (migrants from eastern UP and Bihar) who are spread across the national capital but have concentrated pockets in some parts of the city-state. Over the years, the Purvanchali vote has been aggressively courted by every political party in Delhi. The Congress, during the glory days of Sheila Dikshit’s chief ministership, began Chhath celebrations along the polluted Yamuna riverbed essentially to appease this vote bloc and the AAP continued the practice with gusto. The BJP did its bit to woo the Purvanchalis with ‘rinkiya ke papa’ state chief Manoj Tiwari. Besides the Purvanchalis, Delhi also has an electorally significant concentration of migrants from hill states, particularly Uttarakhand, in assembly segments like Patparganj, Karawal Nagar, Laxmi Nagar and Vishwas Nagar.
