New Delhi, Oct 8 (ANI): A day after Finance Minister P Chidambaram said that it was gross exaggeration to say Gujarat Chief Minister Narendra Modi's wave was sweeping the countryside, the BJP hit back at him saying that the Congress is scared of Modi. Chidambaram while making such remarks had also conceded that Modi - BJP's prime ministerial candidate - has united the rank and file of BJP but he is not bigger than BJP leader and former PM of India Atal Bihari Vajpayee.
