In phase 4 of the 2019 Lok Sabha elections, an estimated 12.79 crore electorate were eligible to exercise their franchise in 13 seats each in Rajasthan and Uttar Pradesh, five in Bihar, eight in West Bengal, three in Jharkhand, six in Madhya Pradesh, 17 in Maharashtra and six in Odisha.

Campaigning for April 29 polling ended on Saturday evening amid allegations and counter-allegations bordering on personal affairs, making it one of the most bitterly fought elections in the country. Prominent candidates on Monday include three Union Ministers: Babul Supriyo West Bengal, Giriraj Singh Bihar and S.S. Ahluwalia also West Bengal. Giriraj Singh, for whom Bihar Chief Minister Nitish Kumar campaigned, is pitted against former JNU student leader Kanhaiya Kumar of the CPI in Begusarai. Kanhaiya Kumar-s candidature has virtually overshadowed the RJD contestant in the seat.
