The yoga guru, however, clarified that it was his personal view.
Ramdev, who was here for a signature campaign on issues regarding Bharat Swabhiman Trust, told reporters that BJP should include people only with 100 per cent clean and nationalist image.
Expressing his anger against the ruling Congress, he said he had travelled 30 to 32 kilometres today and there was angst against the party everywhere, and added that it would not get more than 50 to 60 seats in the coming Lok Sabha elections.
Asked whether he would ever contest elections, the yoga guru said he had taken a resolve never to contest an election.
When asked who between Rajnath Singh and Narendra Modi he sees as a better Prime Minister, Ramdev avoided a direct reply saying "the vision of seers was unbiased".
