He said excessive media coverage to the party had made AAP as the "television opponent" of BJP even when the "field opponent" continued to be Congress.
The Leader of Opposition in Rajya Sabha said a large number of people converge around a party who they consider is a potential winner and there are less claimants of a party which is considered a possible loser.
Terming as unprecedented when candidates decline party nominations after they are publicly announced, he said, "This only happens when candidates find that the prospects of winning are non-existent."
He referred to the Congress candidate from Bhind in Madhya Pradesh deciding to refuse the party nomination and join BJP instead.
He also referred to Chandigarh where AAP claimed to have a sizeable support but its candidate decided to return the party nomination since its cadre in a disarray and she felt there was lack of organisational support for her election.
