Supporters of the present NDA government often say that they are hampered by not having a majority in the Rajya Sabha. At least 10 Rajya Sabha seats are due for election according to the schedule given below. Some more may fall vacant (for instance, Mithun Chakravarthy, a TC member from Bengal, has announced his resignation a few days back).
As we will see in a moment, there will be no significant change in the composition of the Rajya Sabha in 2017, regardless of the assembly elections in Uttar Pradesh and elsewhere.
This table was compiled from the official website of the Rajya Sabha, from where we can deduce who will retire in 2017.
We get this list:
Only Goa’s Assembly will have changed while Gujarat and West Bengal would remain the same at the time of the Rajya Sabha elections in July-August.
In Goa, the one seat held by the INC may go to the BJP (or perhaps the AAP if something very peculiar happens).
In Bengal, the 6 seats are held by the Trinamul (4), INC (1) and CPM (1). Looking at the present constitution of the assembly these seats are likely to go to the same parties (though the CPM is the only one in some danger of losing its seat).
In Gujarat, the 3 seats going for election this year include 2 held by the BJP and 1 by the INC. The elections in August are likely to give the same result.
So one would have to look beyond 2017 to see any significant change in the composition of the Rajya Sabha.
Also, the elections for the President and Vice President are due in July and August respectively and will probably be held before the Rajya Sabha elections described above (though the results of the latter hardly matter).
It may be a source of worry to the NDA that they may not have sufficient strength in the electoral college to be sure of getting their preferred Presidential candidate elected. By then, the assembly elections for UP, Punjab and 3 smaller states will have taken place and present indications are that the NDA will not gain significantly.
This is also apparent for the Vice-Presidential election where the electoral college consists of the Lok Sabha and Rajya Sabha members only.
So 2017 will be a year of numerous elections but, barring some completely unexpected events, they may not result in significant changes to the relative strengths of the main parties and alliances.
