"Highly disappointed with the fate of Congress in Delhi. It's sad to see it like this. Wish Sheila Dikshit was roped in too in the campaign," senior party leader Anil Shastri said on Twitter.
Congress leader Manish Tewari said the poll outcome could have been different had all the leaders participated in the election campaign.
"If collectively everybody would have been pitched into the campaign, it would have possibly made a difference," Tewari said.
Asked what was the way out for Congress as people have rejected the party with a new face this time as well after voting out three-term Chief Minister Sheila Dikshit in last Assembly polls, party's face for this elections Ajay Maken said that the result was a "continuation of 2013 mandate" and more an "affirmation for AAP" than "rejection of any other party".

Congress did not win a single seat losing even all the eight seats it had won earlier in 2013. Besides it lost deposit in the majority of seats this time finishing a poor third in most of them.
