Yadav was adamant on throwing his hat in the poll ring despite several RJD leaders, on behalf of Lalu, urging him not to do so as it would divide the Yadavs, considered the main social support base of the party.
Three Yadavs - ruling Janata Dal-United candidate and sitting MP Ranjan Prasad Yadav, BJP's Ram Kripal Yadav and Misa Bharti of the RJD - are already in the fray that would lead to division of votes.
Last Saturday, Lalu visited Yadav's home in Kthwan village and met the latter's father Ramasish Rai, also the village head.
