Although it being a largest party, BJP refused to form government. After a long dilemma, AAP decided to form government. In fact, it took this dilemma oppertunity into blessing by taking referendum. It formed government.
Kejriwal won hearts step by step with first day. He took oath in very simple manner at Ramlila ground. People attended in large number. He also administered people oath not to give bribe. He came in metro train to reach Ramlila. He also choose 26 year old Rakhi Birla as minister. Not only that, today, he delivered his promise to give 700 liter water free to Delhi residents.
Now from this situation, BJP may be regretting about its decision not to form government. Had it choose to form government without taking any support and delivered good governence it could be a new feather in its cap and it could be beneficial in 2014 elections. But now Kejriwal is gradually emerging as challenge to Narendra Modi, PM candidate of BJP.
