Bhopal/Patna/Ahmedabad, July 29 -- The campaigning for three closely-tracked by-elections in Bihar's Bankipur, Madhya Pradesh's Datia and Gujarat's Manjalpur, to be held on July 30, ended on Tuesday with last-minute canvassing for votes and parties holding rallies and roadshows. In Bankipur, in Patna's urban area, the stage is set for a keenly watched contest among BJP youth wing leader, Neeraj Kumar Sinha, political strategist-turned-leader, Prashant Kishor, from the Jan Suraaj Party (JSP), and RJD's Rekha Gupta. The poll was triggered by the election of five-term MLA and BJP national president Nitin Nabin to the Rajya Sabha in April. Kishor has been the talk of the constituency, personally canvassing nearly every street and lane. He framed the contest as a referendum on the NDA government's performance, particularly targeting chief minister Samrat Choudhary, whom the BJP leadership chose as CM after Nitish Kumar stepped down. Nabin returned to his constituency to campaign, assuring voters that "Bankipur shall remain his top priority" despite new responsibilities. In MP's Datia, the BJP's Ashutosh Tiwari is contesting for the first time while Congress party veteran, Kunwar Ghanshyam Singh, has entered the fray for the seventh time. The assembly seat fell vacant on April 2, after Congress MLA Rajendra Bharti was disqualified under Section 8 of the Representation of the People Act, 1951, and Article 191(1)(e) of the Constitution, following his conviction in a bank scam case. The campaign for Datia ended in the backdrop of internal dissent for both parties. The BJP faced violent protests in Datia after replacing former home minister Narottam Mishra with Tiwari as the candidate. The Manjalpur seat, in Gujarat's Vadodara, fell vacant following the death of BJP MLA Yogesh Patel, a legislator since 1990. While the BJP fielded Satish Patel as its candidate, former minister Bhikhabhai Rabari has been fielded by the Congress party....
