"No one had thought the way this agitation will shape up. Even (AICC General secretary) Digvijaya Singh did not think the movement will shape out this well. Those who challenged us to contest elections even did not think (how well) the way this organisation would shape out," he said.
The AAP leader, who was attacked a few times during road shows, cautioned that attacks against him and his partymen will intensify in the future.
"We cannot fight with the powers whom we took on, with money alone. We took on some of the biggest business houses and political parties of the country. We are not going to stay quiet.
There will be more attacks on us. They (rival parties) are staying quiet because of elections, but after it gets over they will show their true colours," he said.
Kejriwal added that the media will be threatened if BJP comes to power.
"I got some calls from senior editors. They say we have been getting calls from senior BJP leaders who are threatening them. Money is playing a role. People who don't agree with money are being threatened," he said.
