# 2018 elections in India

Elections in the Republic of India in 2018 included by-elections to the Lok Sabha, elections to the Rajya Sabha, elections to of eight states and numerous other by-elections to state legislative assemblies, councils and local bodies.
The elections were widely considered crucial to the ruling National Democratic Alliance and the opposition United Progressive Alliance for the upcoming general elections in 2019. In seven of the eight states that went to polls this year, the Bharatiya Janata Party was in direct contest with the Indian National Congress. Further, the election results in the states of Karnataka, Madhya Pradesh, Telangana, Chhattisgarh, Mizoram and Rajasthan are considered a barometer of the pulse of the public before the general elections. Elections to the upper house where the ruling National Democratic Alliance does not command a majority are by kicking on the part of all the political leaders expected to strengthen its position.

## Background
### Political System

According to the Constitution of India, elections should take place to the parliament and state legislative assemblies every five years, unless an emergency is under operation. Further, any vacancy caused by death or resignation must be filled through an election within six months of occurrence of such vacancy. The elections to the lower houses (in Parliament and in the states) use first past the post system - the candidate with a plurality of the votes wins the election.
Elections to one-third of the seats of the upper house of the Parliament - the Rajya Sabha are conducted every two years. The members of the upper house are elected indirectly by the state legislative assemblies on the basis of proportional representation. Members to the state legislative councils (in states which have an upper house) are elected indirectly through local bodies.
All the elections at the central and state level are conducted by the Election Commission of India while local body elections are conducted by state election commissions.

### Tripura

Elections were held in Tripura on 18 February 2018 in 59 out of 60 constituencies of the Legislative Assembly. The Left Front led by Manik Sarkar sought re-election, having governed Tripura since the 1998 election. The region in general had been under the political control of the Communist Party for 25 years prior to the election, leading to the region being dubbed a "red holdout". The incumbent Left Front government was defeated after 25 years of office, with the Bharatiya Janata Party and Indigenous Peoples Front of Tripura winning a large majority of seats. The Indian National Congress, which was the second largest party in the 2013 election, lost all its seats and most of its vote share.

Elections were held in Karnataka on 12 May 2018 in 222 out of 224 constituencies of the Legislative Assembly. The incumbent Indian National Congress (INC) was seeking re-election, having governed the state since elections in 2013.
