While most of the candidates for the biennial polls spread over 17 states were elected without a contest, balloting appears certain in Karnataka, Rajasthan and West Bengal.
Voting has become imminent for the biennial elections to fill four seats from Karnataka as there are five candidates in the fray - former Union minister B Janardhana Poojary, M V Rajashekharan, Prem Cariappa (all Congress), former Union minister D K Taradevi (BJP) and industrialist Vijay Mallya (independent).
An absorbing battle is on the cards in Bihar where six candidates are in fray for five seats.
The fight will be mainly between actor and BJP MP Shatrughan Sinha, seeking his second term, and expelled Rashtriya Janata Dal leader Ranjan Prasad Yadav, contesting as an independent backed by the JD (U) and the Lokjanshakti Party.
BJP with 35 MLAs in the 243-member house needs six additional votes for a straight victory for Shatrughan Sinha.
The ruling RJD with 115 MLAs and assured support of the 12-member Congress party and some independents is all set to win three seats. Party president Laloo Prasad Yadav is one of the RJD candidates.
Independent nominee and former Union minister Dilip Ray is threatening the prospects of Congress aspirant Maurice Kujur in Orissa where five candidates are vying for four seats.
With 25 MLAs, the Congress requires the backing of five more members to ensure Kujur's victory.
Ray's candidature has been supported by some legislators of the Congress, the BJP and the JMM.
