The Delhi Assembly election result has put the state BJP leadership on the back foot, prompting many, who had campaigned the national capital, to go on a face-saving mode.

The AAP's landslide win has also given a weapon in the hands of the RJD and JDU leadership to attack state BJP leaders and Union ministers from Bihar who had campaigned in Delhi, bringing back memories of how the saffron party had attacked Nitish Kumar and Lalu Prasad after the Jharkhand Assembly elections result.

In the Jharkand Assembly election last year, the RJD and JDU had contested 20 and 10 seats, respectively, with Lalu, Sharad Yadav and chief minister Jitan Ram Manjhi campaigning in the neighbouring state.

State BJP leaders, including Sushil Kumar Modi had taken a dig at Lalu, Sharad and Manjhi, after the Jharkhand Assembly election results, seeking explanation from these leaders to give the vote percentage that RJD and JDU candidates had garnered in the constituencies where they had campaigned.

Modi had also taken a dig at Nitish for not campaigning in Jharkhand fearing defeat. The BJP leadership had also issued a list of constituencies where the RJD and JDU candidates finished third or fourth.

JDU state general secretary Ajay Alok said: "The state BJP leaders now have to give an explanation that despite top BJP state leaders and seven Union ministers campaigning in Delhi to woo Purvanchali voters, why has the party failed to cross even the double-digit figure?"

To woo Purvanchali voters, which comprise around 30 per cent population of Delhi, the central BJP leadership had deputed a battery of state leaders, including Sushil Modi, Union ministers Radha Mohan Singh, Ravi Shankar Prasad, Rajiv Pratap Rudy, Ram Kripal Yadav, Giriraj Singh, Ram Vilas Paswan and Upendra Kushwaha but despite their efforts, the BJP failed to woo Purvanchali voters.

Apart from senior leaders' presence in the Delhi Assembly election, around 200 junior BJP leaders had camped in Delhi for the past 15 days wooing Purvanchali voters.

The Purvanchali voters, which comprise around 30 per cent of the electorate, have influence in around 15 constituencies.

Asked about the performance of candidates seats where BJP leaders from the state had, a politician, who didn't want to be named, said: "Forget the performance of candidates in seats where we have campaigned. Even Prime Minister Narendra Modi's campaign could not ensure a win. We managed to win only three seats."

The leader said the outcome of the Delhi election is a lesson for the party and the central leadership to rethink on its strategy, especially in context of the upcoming Bihar elections.

The politician said there were many factors for the defeat. "The AAP started campaigning three to four months back on local and constituency-specific issues. The BJP was divided and went for negative campaigning. There was also over-dependence on Narendra Modi. The projection of Kiran Bedi acted against the party as well," said the leader.

The effect of the Delhi Assembly election was also felt in Patna, with the state BJP headquarters wearing a deserted look. No senior BJP leader was present at the party office.

BJP MLA and party chief spokesperson Vinod Narayan Jha, who had camped in Delhi for 15 days, was seen watching the election results on TV. Jha said: "Defeat and victory are part of elections. Even we are clueless why the party has performed so badly."
