The Tarapur assembly constituency has 2,72,596 eligible voters among them 1,46,368 male and 1,26,223 female voters.
One of the three assembly constituencies located in the Munger district of Bihar, Tarapur is currently held by Neeta Choudhary of the Janata Dal (United) who won the seat by defeating her nearest Rashtriya Janata Dal (RJD) rival Shakuni Choudhary by a margin of 13878 votes in the last general assembly elections to Bihar in 2010. In that election to Tarapur while Neeta Choudhary polled 44582 votes, Shakuni Choudhary, a six term MLA, received 30704 votes.
Jamalpur and Munger are the other two assembly constituencies located in Munger district. Both are currently represented by JD (U) legislators.
Veteran Bihar politician Shakuni Choudhary had won the Tarapur assembly seat in 1985, 1990, 1995, 2000 and both the elections held in 2005. While he emerged victorious in 1985 as an Independent candidate, his win in the next assembly elections in 1990 came as a Congress nominee. In 1995 he claimed the seat on the ticket of Samata Party, the earlier avatar of Janata Dal (United). He resigned from the Tarapur seat in 1998 after his election to the Lok Sabha on the ticket of Samata Party.
The byepoll to the Tarapur constituency in 1998, necessitated due to his resignation, sent his wife Parvati Devi to the Bihar legislative Assembly. Shakuni Choudhary lost the 2009 Lok Sabha election to Bhagalpur to Shahnawaz Hussain of the BJP by 55,811 votes.
Shakuni Choudhary later joined the Lalu Prasad led RJD and successfully contested 2000 and both the elections held in 2005 on the party ticket. He joined the JD(U) in 2014.
In 1980, Tarapur assembly constituency went in favour of the Communist Party of India (CPI) whose candidate Narayan Yadav emerged victorious from the seat by defeating former Congress MLA Tarni Prasad Singh.
Tarapur is one of the six assembly segments the combination of which goes on to create the parliamentary constituency of the same name which is currently represented by Chirag Paswan of the LJP who won it by defeating his nearest RJD rival Sudhansu Shekhar Bhaskar in 2014 Lok Sabha elections. The JDU nominee and Bihar speaker Uday Narayan Choudhary was relegated to the third place.
Jhajha, Jamui, Chakai, Sheikhpura and Sikandra are other five assembly segments located in the Lok Sabha constituency of Jamui, reserved for candidates belonging to scheduled castes.
No party seems to have fielded candidates who have clean records. Some candidates in their affidavits to the EC have declared the number of cases pending against them. Shakuni Choudhary of Hindustani Awam Morcha (Secular) from Tarapur constituency has declared he has a case agaisnt him related to injuring or defiling place of worship with intent to insult the religion of any class (IPC section-295).
Sanjay Kumar, one of the Munger district Congress vice-presidents, is contesting as an Independent from Tarapur against the official JD(U) candidate Mewalal Chaudhry. Tarapur seat in Munger district is much influenced by money power and 'mahua'. Only the Yadav-dominated pockets appear to be loyal to any party.
