One of the six assembly constituencies in the Aurangabad district of Bihar, Kutumba is currently represented by Lalan Ram of the Janata Dal (United) who won it in the last assembly elections by defeating Rashtriya Janata Dal (RJD) candidate Suresh Paswan by a good margin of 13910 votes in a bipolar contest.
In the only assembly election to Kutumba, which came into being before the last general assembly elections in 2010 following the recommendations of the Delimitation Commission, whereas Lalan Ram, a Mahadalit and former Maoist, polled 42559 votes, Suresh Paswan, former minister, received 28649 votes and was followed by Rajesh Kumar of the Congress who managed to secure 8477 votes.
Goh, Obra, Nabinagar, Aurangabad and Rafiganj are the other five assembly segments that fall in the Aurangabad district.
In 2010 assembly elections since the BJP was in alliance with the Janata Dal (United) the party did not field its candidate for the Kutumba assembly seat. However, as things stand today, the BJP and the JD (U) have parted ways and the Lok Janashakti Party (LJP), then an ally of the RJD, is now a part of the BJP led NDA, the ruling dispensation at the Centre.
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.
Kutumba is one of the six assembly segments the combination of which goes on to create the parliamentary constituency of Aurangabad currently held by Sushil Kumar Singh of the BJP who had won the seat in 2014 Lok Sabha elections by defeating Nikhil Kumar of the Congress by a margin of 66347 votes. Nikhil Kumar is a former Delhi police commissioner and governor of Nagaland and Kerala.
Aurangabad, Rafiganj, Gurua, Imamganj and Tikari are the other five assembly seats that are parts of Aurangabad Lok Sabha constituency.
Former Bihar CM Jitan Ram Manjhi has given ticket to his son Santosh Kumar Suman from Kutumba (reserved SC) seat in Aurangabad. Santosh is pitted against Rajesh Kumar from Congress. However, given the overwhelming support from mahadalit communties, HAM candidate is expected to sail through easily. Jan Adhikar Party led by its chief Pappu Yadav has fielded Sudeshewar Kumar in Kutumba.
