New Delhi: Bharatiya Janata Party (BJP) leader Rajiv Pratap Rudy on Saturday said Bihar Chief Minister Nitish Kumar is sensing defeat in the upcoming Bihar assembly polls and that is why has become irritable and combative. “The bitterness which Nitish Kumar reflects in his statement against the prime minister is the same as what Kejriwal did and does in Delhi. He spits venom against the prime minister and the union government,” Rudy told ANI. “People in Delhi are already regretting the fact that they elected Kejriwal. I am sure the people in Bihar will not make the mistake of electing Nitish Kumar and expressing regret later,” he said.
