The Congress has still not been able to finalise its candidate for the one of the two Rajya Sabha seats that will fall in its kitty. The last date for filing nominations is tomorrow and at least 10 leaders have staked their claim or the party ticket.Sources said that the party high command’s dilemma lies in balancing the various factions within the Congress and find a “neutral” candidate.Among to top contenders are sitting Congress state chief Rao Narendra Singh, former MLA Rao Dan Singh and former minister Capt Ajay Yadav, all Ahir leaders.Though actor-turned-politician Raj Babbar and Anand Sharma were in the reckoning for the party ticket, sources in the party said that the High command wanted to go with an “insider” over an “outsider”. Among the SC candidates vying for the ticket are former state chiefs Ashok Tanwar and Udai Bhan. While Tanwar who re-joined the Congress ahead of the assembly polls is a “hot contender”, leader of Opposition Bhupinder Singh Hooda is keen on sending Bhan to the Rajya Sabha.Sources said that the other faction of MP Kumari Selja and RS MP Randeep Surjewala are backing Rao Narendra Singh.However, the party, according to leaders, is keen on playing the SC card since Hooda, a Jat, is the Leader of Opposition, Rao Narendra is state chief and the SCs are yet to get representation. By appointing an Ahir, OBC caste, as state chief Ahir, the party broke away from the conventional Jat-SC combination which has led the party for long.Now, sources say, the party wants to give representation to the SC lobby provided it is able to balance the party equations.The term of two Rajya Sabha members—Kiran Choudhry and Ramchandra Jangra—will end on April 9. To fill the seats falling vacant due to the completion of their tenure, the schedule for the biennial election was notified last week.While nominations for both seats can be filed until March 5, scrutiny of nomination papers will be done on March 6, and candidates would be permitted to withdraw their names until March 9. If required, polling will be held on March 16.
