The electoral race is tantalisingly poised in the politically crucial Hindi heartland states of Madhya Pradesh and Chhattisgarh, where the ruling Bharatiya Janata Party (BJP) and the Congress are locked in a neck-and-neck contest, with the latter having the edge in Rajasthan, according to exit polls published on Friday after the conclusion of voting in the last round of state elections before the 2019 Lok Sabha polls.Chief minister K Chandrasekhar Rao’s Telangana Rashtra Samithi (TRS) has an advantage in Telangana in the south, and Zoramthanga’s opposition Mizo National Front (MNF) may edge past the Congress in Christian-majority Mizoram, showed the polls published after voting drew to a close on Friday in Telangana and Rajasthan.Exist polls are conducted just after a voter walks out of the polling booth after casting his or her vote. They are aimed at predicting the result of an election on the basis of information collected from voters.

The results will be announced after the votes are counted on December 11.The BJP, which had Prime Minister Narendra Modi and party president Amit Shah at the vanguard of its campaign,is trying to win power for a fourth straight term in Madhya Pradesh and Chhattisgarh and trying to retain Rajasthan, which has a tradition of alternating between the ruling party and the main opposition, which this time is the Congress.The Congress, whose campaign was spearheaded in all states by party president Rahul Gandhi, is hoping to benefit from an anti-incumbency vote in Rajasthan against the government of Vasundhara Raje.“The anger was very palpable against the BJP in these elections and people were willing and happy to accept the blueprint given by the Congress,” senior Congress leader Sachin Pilot, who is also party’s contender for the top post in Rajasthan, said. “People want answers for questions which they have avoided for the last five years as price rise, farmers are in distress and the economy is collapsing.” Also Read: Exit polls show close contest in MP, Chhattisgarh; give Rajasthan to Congress He added: “It is very easy to see that the BJP is on the backfoot in all these five state assembly polls and the Congress is giving an alternative which most people are endorsing and that is the take away from these exit polls.”A better result for the Congress will be a morale booster for the opposition party and its president, Rahul Gandhi, after series of debacles in state elections since the 2014 general election. Earlier this year, the party formed a post-poll alliance with the Janata Dal (Secular) to retain power in Karnataka, where the BJP emerged as the single largest party.BJP spokesman GVL Narasimha Rao said: “The Congress can gloat over exit poll results, but this happy feeling would be shortlived.”The TRS, which spearheaded the Telangana statehood campaign that culminated in the creation of India’s youngest state out of Andhra Pradesh in June 2014, took a gamble in September when it opted for early elections and CM Rao, better known as KCR, dissolved the assembly. KCR is facing a united challenge from the Congress, the Telugu Desam Party (TDP) and the Left that have formed a ‘mahakootami’ (grand alliance) to unseat the TRS.The Congress could win anywhere between 101 and 145 seats in Rajasthan, according to separate exit polls conducted by ABP-CSDS Lokniti, India Today-Axis, Republic C-Voter and Times Now-CNX.
