"Yadav is a tall national leader who must sit in Parliament and continue to raise voice on behalf of the poor and deprived sections of the society," he told an election meeting at Sonbarsa high school ground in favour of the JD(U) national president.
"The onus is on you (voters) to ensure Yadav's victory from Madhepura this time too," Kumar said in an emotional appeal to the electorate of Madhepura parliamentary constituency.
"The BJP candidate is a vote 'katwa' (one who gets enough votes to turn the outcome) who has been put up to take away votes from the JD(U) to ensure the RJD nominee's victory," he said.
Kumar, who is single-handedly spearheading JD(U)'s campaign in Bihar, hit out at the BJP for resorting to communal and divisive agendas to grab power at the Centre.
"I may bite dust in public life, but will never make compromise with secularism," the chief minister remarked.
