The general elections in 2019 saw the NDA win big. But in Mumbai, three of six constituencies had a different story to tell even with alliance candidates winning, as their lead margins were reduced. The constituencies of North East, South Mumbai and North Central, saw their winning margins reduced, as compared to the elections in 2014.

The North East constituency, one of the Bharatiya Janata Party's (BJP) strong holds with a majority of Gujarati speaking people, had a new candidate, Manoj Kotak, instead of sitting MP Kirit Somaiya. In the 2014 contest, the winning margin here between the BJP and Nationalist Congress Party was 3.17 lakh votes, which in 2019 came down to 2.26 lakh. Sources revealed that the change in candidate could have been one of the reasons for the reduction in the winning margin.
