The Congress on Tuesday hailed its good showing in assembly polls in three Hindi heartland states and thanked people for choosing "love over hate".
The Congress appeared set to wrest Rajasthan and Chhattisgarh from the BJP, which was trailing marginally in Madhya Pradesh in a cliffhanger.
"Democracy has won! Thank you India, you have chosen love over hate, peace over violence & truth over lies. This victory is yours," read a tweet on the party's official Twitter handle, with the hashtag 'CongressWinsBIG'.
In a shock result, a resurgent Congress ended Chief Minister Raman Singh's uninterrupted 15-year rule in Chhattisgarh and was on course to regain power in Rajasthan, where the BJP won all the 25 seats in the 2014 Lok Sabha election.
