Yadav has won four terms from the seat. He has also won twice from Jabalpur in Madhya Pradesh and once from Badaun seat in Uttar Pradesh. These elections, he is facing a stiff challenge.
The JD(U) candidate from Madhepura added he was upset with the "unfair" manner in which the media was covering the ongoing elections. Asked about his own prospects, Yadav said he was always 'mast' (free of tension).
Lashing out at a TV reporter who asked him about his credentials as a socialist of eminence, Yadav said, "Samajwad (socialism) means that the people should be of high quality."
Yadav's challengers in Madhepura are RJD strongman Rajesh Ranjan, alias Pappu Yadav, and BJP's Vijay Singh Kushwaha, husband of legislator Renu Kumari.
Kumari had resigned as a minister in the Nitish Kumar government last month after Singh joined the saffron party. She was suspended from the JD(U).
