While Jha is trying his luck on a JD(U) ticket from Paschim Champaran, more popularly known as Bettiah, Raghubansh Prasad Singh, who won praise for piloting MGNREGA, is fighting from his traditional Vaishali seat on a RJD ticket.
Singh is pitted against muscleman-politician Rama Singh of the LJP and Vijay Kumar Sahni of the JD(U).

Elaborate security arrangement has been made for the last round of election with 58,000 security personnel put on duty while armed personnel would be posted at every polling location.
The Election Commission reduced poll timings by two hours in five assembly segments in view of perceived Maoist threat.
Voting began this morning in 17 constituencies in the last of the 5-phase Lok Sabha election in West Bengal to decide the fate of 188 candidates.
While the ruling Trinamool Congress would strive to retain all 14 of the 17 seats it had won in the 2009 Lok Sabha election, the Left Front's efforts would be to wrest some among the 17 which it had lost last time.
An electorate of 2,55,75,744 is eligible to vote in the crucial round.

Polling began this morning on a peaceful note for 18 seats in the crucial last phase of Lok Sabha polls in eastern Uttar Pradesh, to decide the fate of 328 candidates, including BJP's Prime Ministerial candidate Narendra Modi, AAP's Arvind Kejriwal and SP supremo Mulayam Singh Yadav.
"The polling has started on a peaceful note and will continue till 6 pm. Elaborate security arrangements have been made for this phase", UP Chief Electoral Officer Umesh Sinha said.
Over 3 crore voters, including 1.42 crore women, are expected to exercise their franchise at 19,881 polling centres to decide the fate of 328 candidates including 14 women and various political stalwarts.
In the mother of all political battles, Kejriwal will take on Modi from the the temple city of Varanasi, which witnessed massive show of strength by both the outsiders, also attracting the attention of international media.
Congress' Ajay Rai, a 'local' backed by Mukhtar Ansari's Quami Ekta Dal (QED), also wooed voters here as the high pitched canvassing saw allegations and counter-allegations flowing thick and fast between leaders of different hues.
On these 18 seats, Samajwadi Party had clinched six seats from the region, BSP (5), BJP (4) and Congress (3) in 2009 Lok Sabha polls.
Interestingly, BSP had registered marginal loss and ended up in the second place in 12 seats.
The Samajwadi Party supremo, besides sticking to his traditional bastion in Mainpuri, has thrown his hat into the ring from Azamgarh too.
However, unlike Mainpuri, Azamgarh may not be a cakewalk for him as he faces a tough fight from BSP's Shah Alam alias Guddu Jamali, Rastriya Ulema Council Chief Aamir Rashadi Madani, and Mulayam's former associate Ramakant Yadav, who is now fighting on a BJP ticket.
While Mulayam is banking on his traditional Muslim-Yadav vote bank, division of Muslim votes by Madani and Guddu Jamali could benefit Ramakant.
