Patna/Bhubaneswar, March 16 -- Hectic political activity was witnessed in three states - Bihar, Odisha and Haryana - where voting will be required to elect 11 seats in the Rajya Sabha polls on Monday, even as 26 seats across seven states are set to be elected unopposed. The biennial elections are being held for 37 seats - seven in Maharashtra, four in Odisha, six in Tamil Nadu, five in West Bengal, three in Assam, five in Bihar, two in Chhattisgarh, two in Haryana, one in Himachal Pradesh and two in Telangana. The NDA, which is in power in six of the 10 states that are going to the polls for the Upper House, has 134 members in the 234-strong Rajya Sabha and is set to increase its count. The Opposition INDIA bloc, which is in power in four states, holds 80 seats. The counting will be held on the same day. In Bihar, the NDA camp seemed confident of making a clean sweep on all five seats with three key leaders - Nitish Kumar (JD-U), Nitin Nabin (BJP) and Upendra Kushwaha (RLM) - in the fray. The other two NDA candidates are Union minister Ram Nath Thakur of the JD(U), who aims at a hat-trick and BJP state general secretary Shivesh Kumar. The RJD, meanwhile, is banking heavily on the support of All India Majlis-e-Ittehad-ul-Muslimeen (AIMIM), which has five MLAs. In Odisha, the biennial RS elections for four seats have descended into a high-stakes political drama, with the state Congress issuing a show-cause notice to a missing MLA while two men were arrested in Karnataka for allegedly attempting to bribe legislators, and the BJP ferrying its MLAs to the port town of Paradip for "voting procedure training". In Bengaluru, two people from Odisha were arrested after allegedly sneaking into a resort where eight of the 14 Congress MLAs of the state are being housed and approaching at least one legislator with a blank cheque. Ashok Kumar Das, deputy leader of the Odisha Congress Legislature Party, said he has lodged a complaint against four unknown people who offered MLAs "crores of rupees each" to cross-vote, and that when the offer was rejected, they threatened to kill them. Separately, the Congress on Sunday show-caused its MLA Dasarathi Gamang over his "disappearance". The BJP, meanwhile, moved its MLAs to Paradip on Saturday evening, accompanied by the two deputy chief ministers, for a training session on Rajya Sabha voting procedure. Chief minister Mohan Charan Majhi arrived in Paradip on Sunday to oversee the preparations. The MLAs are scheduled to depart Monday directly to cast their votes. BJD chief Naveen Patnaik continued to meet party MLAs at his residence for the third consecutive day appealing them to desist from cross-voting. The parties have issued three line whips to MLAs to be present in assembly. The four seats in Odisha were vacated by the expiry of terms of BJD's Niranjan Bishi, Munna Khan, and BJP's Sujeet Kumar and Mamata Mohanta on April 2. Two Rajya Sabha seats would fall vacant in Haryana as BJP members Kiran Choudhry and Ram Chander Jangra are set to complete their terms on April 9. In Maharashtra, all seven candidates, including six of the ruling Mahayuti and NCP chief Sharad Pawar, are set to be elected unopposed. In Tamil Nadu, DMK's Tiruchi Siva and J Constantine Ravindran, Congress's M Christopher Tilak, DMDK's LK Sudeesh, AIADMK's M Thambidurai, and PMK's Anbumani Ramadoss are set to be elected unopposed to the state's six Rajya Sabha seats. In Telangana, Congress's Abhishek Manu Singhvi and Vem Narender Reddy were elected unopposed to the state's two Rajya Sabha seats. In West Bengal, TMC's Babul Supriyo, former state DGP Rajeev Kumar, senior Supreme Court advocate Menaka Guruswamy and actor Koel Mallick and BJP's former state unit president Rahul Sinha are in the fray....
