New Delhi, Dec 10 : Congress defeat in the three Hindi heartland states of Chhattisgarh, Madhya Pradesh, and Rajasthan was "unprecedented" as it was expecting to win in two states at least, a party source said.

The source said that the party had held four back to back review meetings to discuss the losses in the recently concluded Assembly polls. 

He admitted that the results in the four states were "unprecedented" and no one expected to lose in Chhattisgarh.

However, the source said that polarisation was witnessed on ground in Rajasthan and Madhya Pradesh.  The source also said that the party was expecting 90 seats in Rajasthan as anti-incumbency was not there but there was anger against many of the sitting MLAs. He also admitted that the party was on defensive mode in Rajasthan due to two camps.
