Supriya Sule, daughter of Sharad Pawar, is leading against Sunetra Pawar, wife of cousin Ajit Pawar, in Baramati Lok Sabha seat in what is billed as a Pawar vs Pawar contest.
Playing down the contest between the two, Ms Sule had said Sunetra Pawar is the wife of her "elder brother and the elder sister-in-law is considered a mother."
Ms Sule is contesting this seat for the third time, while Sunetra Pawar is making her political debut in this election.
The Baramati Lok Sabha constituency has been a stronghold of Sharad Pawar since the 1960s, Ajit Pawar has been a successful MLA from Baramati since 1991.
An "emotional tactic" is how Deputy Chief Minister Devendra Fadnavis described Ms Sule's move to meet Ajit pawar's mother Ashatai Pawar in Baramati right after voting.
