In Gujarat, the contest is likely to go down to the wire as both the ruling BJP and the opposition Congress do not have absolute numbers in the assembly to get all their candidates win on their own.

The BJP has fielded three candidates -- Abhay Bharadwaj, Ramila Bara and Narhari Amin -- for the four seats, while the Congress, which has seen desertions in its legislative ranks, has given tickets to two nominees Shaktisinh Gohil and Bharatsinh Solanki.

The BJP, with its current numbers in the 182-member assembly, can win two seats, while the Congress on the basis of its House strength can bag one. A tough fight is expected for the fourth seat.

Notwithstanding their respective numbers, both the parties have expressed hope that all their candidates will sail through.

Considering that the effective strength of the assembly is reduced to 172, a candidate will require support of minimum 35 MLAs to win, as per the RS election standard formula. Ten assembly seats are currently vacant -- eight due to resignations of Congress MLAs and two due to court cases.

With 65 MLAs and one independent (Jignesh Mewani) supporting its candidates, the Congress will still need the backing of four more MLAs to win both the seats. While the BJP's House strength is 103, it will require support of 105 MLAs to win the three seats.

The faith of the fourth seat will be decided by the two Bharatiya Tribal Party MLAs and one of the Nationalist Congress Party.

For the three seats up for grabs, four candidates (two from Congress and as many from BJP) have filed nomination papers. The Congress has nominated K C Venugopal and Neeraj Dangi, while the BJP has fielded Rajendra Gehlot and Onkar Singh Lakhawat.

In the house of 200, the Congress has 107 MLAs and has the support of independent MLAs and legislators of other parties like Rashtriya Lok Dal, CPI-M and BTP.

The ruling party has more than enough majority to win two seats and the opposition BJP, which has 72 MLAs and support of three Rashtriya Loktantrik Party MLAs, has the numbers to comfortably win one seat.

Fifty-one votes are needed for one candidate to win and the Congress is in a comfortable position to ensure the victory of both of its candidates, while BJP's only one candidate can win as per the numbers.

After 51 votes to its first candidate Rajendra Gehlot, BJP's spare votes will go to second candidate Onkar Singh Lakhawat.

In Andhra Pradesh, the ruling YSR Congress is poised to win all the four seats given its formidable strength in the state assembly. This is the first time that an election is being conducted for Rajya Sabha seats from the state, post-bifurcation in 2014.

From the YSRC, Deputy Chief Minister Pilli Subhash Chandra Bose, minister Mopidevi Venkata Ramana Rao, realtor A Ayodhya Rami Reddy and Reliance Industries Senior Group president Parimal Nathwaniare in the fray. The TDP has fielded its politburo member Varla Ramaiah.
