There are 2,21,967 people in the Morwa legislative assembly segment amongst them 1,18,619 are men and 1,03,339 are women. Morwa assembly constituency will cover Fatehpur, Muradpur Bangra, Rajwa, Gauspur Sarsauna, Rahimabad, Kothiya, Ramapur Maheshpur, Manpura, Kaswe Aahar, Harishankarpur Baghauni, Dhgharua and Madhopur gram panchayats of Tajpur community development block; Bahadurpur Patori, Sirdilpur Supaul, Imansarai, Hasanpur Surat, Darba, Jorpura, Chaksalem and Shahpur Undi of Patori community development; and Morwa community development block.
One of the ten assembly constituencies located in the Samastipur district of Bihar, Morwa was won by Baidhnath Sahani of the Janata Dal (United) in the last assembly polls to Bihar in 2010. In that election, Baidhnath Sahani had polled 40271 votes to defeat Ashok Singh of the Rashtriya Janata Dal (RJD) by a margin 6850 votes. Ashok Singh received 33421 votes and was remotely followed by Nagmani of the Congress who secured just 6995 votes.
Former union minister Nagmani was elected from the Kurtha assembly seat in 1977 as a nominee of the now defunct Soshit Samaj Dal founded by his father and former deputy Chief Minister Jagdeo Prasad. Known for switching loyalties at the drop of hat Nagmani had also won the Kurtha seat in 1995 as an independent.
In 2010 the BJP did not field its candidate for the Morwa assembly seat because it was in alliance with the Janata Dal (United) at that time. However, since elevation of Narendra Modi was not liked by Nitish Kumar, the JD (U) snapped the ties with the BJP. As things stand today, the Lok Janashakti Party (LJP), previously an ally of the RJD, is now a part of the BJP led NDA, the ruling dispensation at the Centre. Due to abysmal performance of the JD (U) in the 2014 Lok Sabha polls, the JD (U) and RJD have joined forces with the Congress to stop the BJP from coming to power in Bihar.
In 2010 the BJP had won 91 seats whereas the JD (U) managed to claim 115 seats, becoming the single largest party. While the RJD put up a dismal performance with only 22 seats, the Congress was able to win only four.
Morwa assembly constituency, which came into being before the last general assembly polls in 2010, is one of the six assembly constituencies that combine to form the parliamentary constituency of Ujiarpur which is currently represented by Nityanand Rai of the BJP who won the seat in the 2014 Lok Sabha elections by defeating his nearest RJD rival Alok Kumar Mehta by a margin of 60,469 votes.
Other five assembly constituencies that are parts of the Ujiarpur parliamentary seat are Bibhutipur, Patepur, Ujiarpur, Sarairanjan and Mohiuddinnagar.
In Morwa constituency, BJP candidate Suresh Rai will have to face opposition from his own people as party rebel Abhay Kumar Singh has filed nomination. Morwa constituency has a maximum of 18 candidates in Samastipur district. And caste equations, rebel activities within parties and youth power are critical factors in deciding the fate of candidates.
