"BJP does not have a face. It does not have even a second-rung face let alone a leader who can take on Arvind Kejriwal," AAP leader Yogendra Yadav told reporters here.
AAP has a fair chance as a significant sections of voters who had voted for Narendra Modi as the Prime Minister prefer to see Kejriwal as Delhi Chief Minister, Yadav said.
He also said that AAP would benefit as Congress is facing a near wipe out.
"The Congress faces a near wipe out in Delhi as it is expected to garner five to six per cent of votes. Most of the votes that Congress loses will come to AAP," he said.
Resurgence of AAP among the working class after facing serious challenge among the middle class following the resignation of Kejriwal as Delhi Chief Minister, will benefit the party in the ensuing elections, Yadav said.
"The Lok Sabha verdict is not going to be repeated in Delhi as BJP was not confident of facing an election... Things have levelled, and that is why BJP itself was so nervous about holding elections," he said.
Yadav alleged that there is "Congressisation" of BJP all over the country. "Whereever the BJP is spreading it is adopting the ways of the Congress. This is the Congressisation of BJP all over the country," he said.
"If you look at the blackmoney situation and how the BJP has taken a U-turn. You look at question of FDI and Insurance ... And you find BJP following exactly same policies followed by Congress," he said.
"One thing is very clear (from the electoral defeat faced by Congress in Lok Sabha and assembly elections in Maharashtra and Haryana) that Congress may cease to exist as a nationwide opposition in next four to five years," he said.
Yadav said whenever the Congress has fallen below 20 per cent of the electoral votes in states in the last two decades, it has never been able to bounce back. "Tamil Nadu, West Bengal, Uttar Pradesh, and Bihar tell us the same story."
The absence of an opposition party creates a vacuum in the political space and at the moment, there was no political party that could fill the gap, Yadav said.
