The Congress is likely to unseat the BJP from power in Rajasthan, two opinion polls have predicted, in what could be a continuation of the state's tradition of over two decades of voting out the ruling party.

Surveys carried out by ABP News-C Voter and C fore have given the Congress almost 50 per cent of the vote share and 142 and 124-138 seats respectively in the 200-member Rajasthan Assembly, with its state president Sachin Pilot leading Chief Minister Vasundhara Raje as the most preferred candidate for the top post.

While the C fore survey is restricted to Rajasthan, the ABP News-CVoter opinion poll has also predicted the outcome of the Assembly elections in BJP-ruled Madhya Pradesh and Chhattisgarh, giving an edge to the Congress in both the states.

The BJP is in power in Madhya Pradesh and Chhattisgarh for 15 years.

The pre-poll survey has, however, added that a minor swing in both the states can turn the tide in the favour of either of the two main parties due to a very small difference between their projected vote shares.

It has predicted 122 seats for the Congress in the 230-member Madhya Pradesh Assembly and 47 seats for the opposition party in the 90-member Chhattisgarh Assembly. The BJP has been projected to bag 108 and 40 seats in these two states respectively.

The Bharatiya Janata Party (BJP) had on Saturday expressed confidence that it would register a "record victory" in the upcoming state Assembly elections and retain power in Madhya Pradesh, Chhattisgarh and Rajasthan.

Senior BJP leader and Law Minister Ravi Shankar Prasad had said the BJP would secure a record victory on the basis of its hard work and development measures, besides the performance of its governments in the three states.

In Rajasthan, Mr Pilot leads Ms Raje as the popular choice for the chief minister's post with 36 per cent voters preferring him, while the latter is the first choice for 27 per cent, according to the ABP News-CVoter poll, which says former chief minister and Congress leader Ashok Gehlot enjoys the backing of 24 per cent voters.

The C fore poll says Mr Pilot, Mr Gehlot and Ms Raje are the first choice of 32, 27 and 23 per cent voters respectively.

However, Madhya Pradesh Chief Minister Shivraj Singh Chouhan and his Chhattisgarh counterpart Raman Singh are the first choice of the voters for the hot seat, despite anti-incumbency sentiments against their governments, the ABP News-CVoter poll says.

The Congress and the BJP have been predicted to bag 42.2 and 41.5 per cent votes in Madhya Pradesh and 38.9 and 38.2 per cent votes in Chhattisgarh respectively.

There is, however, a huge gap in the projected vote share of the Congress and the BJP in Rajasthan, with the opposition party being backed by 49.9 per cent voters against the 34.3 per cent share for the ruling dispensation.

The vote share predicted by C fore is 50 and 43 per cent for the Congress and the BJP respectively in Rajasthan.

The BJP had secured power in all the three states in 2013 by winning 165, 142 and 49 seats in Madhya Pradesh, Rajasthan and Chhattisgarh respectively as against the 58, 21 and 39 seats of the Congress.

The C fore survey interviewed 5,788 voters in Rajasthan, while the ABP News-CVoter opinion polls had a sample size of 26,196 voters in the three states.

The Election Commission (EC) on Saturday announced that the Assembly polls in Chhattisgarh, Madhya Pradesh, Mizoram, Rajasthan and Telangana will be held between November 12 and December 7.

While Chhattisgarh will go to the polls in two phases on November 12 and 20, the elections in Madhya Pradesh and Mizoram will be held on November 28.

Polling in Rajasthan and Telangana will be held on December 7 and the counting of votes will be taken up in all the five states on December 11.
