These three parties have forced the elections in eastern Uttar Pradesh to be contested on caste arithmetic.
The Suheldev Bhartiya Samaj Party (SBSP) was a BJP ally till recently when its President Om Prakash Rajbhar declared that he was snapping ties with BJP and fielding his own candidates in the elections.
Political pundits are now speculating the extent of damage that Rajbhar could cause the BJP in the final phase.
The Nishad Party, which has emerged as a force to reckon with in recent months, enjoys the support of the Nishad community in Gorakhpur and in districts along the Ganga river.
Though the Nishad Party is supporting the BJP, the Nishad community, by and large, is upset with the BJP which has not fulfilled its promise of installing a statue of Nishad Raj in Gorakhpur.
The caste slant in the final phase of elections is evident from the fact that even Prime Minister Narendra Modi had to underline the fact that he belonged to the OBC category in his election speeches.
The OBC votes in the final phase will play a decisive role since they form almost 40 per cent of the voter population.
