The districts which brought down the 15-year-old regime of Lalu Prasad Yadav in 2005, will go to the fourth phase of the Assembly elections on November 1.
The 42 assembly seats are spread over Patna, Bhagalpur, Munger, Sheikhpra, Jamui Begusarai, Khagaria and Lakhisarai districts.
Prominent among 575 candidates in the fray, are state BJP stalwarts and ministers, Ashwini Kumar Choubey (Bhagalpur), Nand Kishore Yadav (Patna Sahib) Ramnarayan Mandal (Banka), besides JD(U) minister Damodar Raut.
While JD(U) is contesting from 25 seats, ally BJP is contesting in the remaining 17.
RJD has fielded candidates in 25, and ally LJP in 17.
The Congress and BSP have fielded candidates in all the constituencies.
The CPI-ML (L) is contesting 15 seats, CPI 13 seats while CPI-M is contesting six seats.
In 2005 October, an upsurge was witnessed in favour of the NDA, while the RJD-LJP combine was halved in each district.
The poor performance of RJD was the result of the LJP of Ramvilas Paswan ploughing a separate furrow and substantially split the minority votes of Lalu Prasad.
