Political activity in the Indian State of Kerala takes place in a multi-party democratic framework, within the overall context of the National Politics of India. The state holds an invariable position of having the largest politically aware and active population in the Country. The state Legislature is unicameral and has a membership of 141, where 140 are elected and one is nominated from the Anglo-Indian community. It has 20 seats in the Lok Sabha and 9 seats in the Rajya Sabha. Elections are also held to choose representatives to the civic bodies at various levels within the State. and The State has consistently come out with a voter turnout of 70% or above in almost all elections which was ever held.
Politics in Kerala is dominated by two coalition fronts: the Communist Party of India(Marxist)-led Left Democratic Front (LDF) and the Indian National Congress-led United Democratic Front (UDF) since late 1970s. These two coalitions have been alternatively voted to power since 1982. Most of the major political parties in Kerala, except for Bharatiya Janata Party (BJP), belong to one or the other of these two alliances and have in the past shifting allegiances a number of times. In Kerala, it is difficult for a single party to contest and win even a single seat, because the voter perception is towards voting for a front. The BJP has been able to register its presence with one seat in Nemom in the assembly in spite of the fact that it is the third largest party in Kerala after Congress and CPM. According to 2016 Kerala Legislative Assembly election results, the LDF has a majority in the State Assembly (91/140). The political alliances have stabilized strongly in such a manner that, with rare exceptions, most of the coalition partners stick their loyalty to the respective alliances. As a result of this, ever since 1979, the power has been clearly alternating between the two fronts without any exceptions. However, till then the political scenario in Kerala was characterized by continually shifting alliances, party mergers and splits, factionalism within the coalitions and within political parties, and the formation of a numerous splinter groups.
