That Mainpuri assembly constituency is a stronghold of Samajwadi Party (SP) can be gauged from the fact that in the 2014 Lok Sabha elections, the SP supremo Mulyam Singh Yadav had established a massive lead of 45974 votes over his nearest BJP rival Shatrughan Singh Chauhan in the Mainpuri assembly segment in spite of the Modi wave which found its fullest expression in the state of Uttar Pradesh. The main contest for 2017 assembly election will be between SP and BJP.
