Contradicting all exit polls but one and beating the state's tradition of strong anti-incumbency swings, Chief Minister J Jayalalithaa was elected for a second consecutive term on Thursday. The last chief minister who was re-elected was AIADMK's M G Ramachandran, in 1984. Counting of votes began in Tamil Nadu at 8 am amid tight security, while supporters gathered outside Jayalalithaa's home and Opposition party leader Karunanidhi's residence.

The state recorded a voter turnout of 74.2% in 232 Assembly constituencies. Around 4.28 crore voters chose between 3,800 candidates in 232 constituencies in the May 16 polls. Exit polls had predicted a win for Opposition party Dravida Munnetra Kazhagam. The state has swung between the DMK and incumbent All Indian Anna Dravida Munnetra Kazhagam since 1972, a trend that pointed to an AIADMK loss this time. However, a few hours into counting, trends showed a win for Jayalalithaa.

Though Jayalalithaa saw a historic win, the People's Welfare Front did not win a single seat. In the end, the AIADMK won 131 of the state's 226 seats.

Jayalalithaa contested from RK Nagar constituency, north of Chennai, which is considered a safe seat for the AIADMK. The party has won every assembly election here since 2001. In the 2015 bypoll, Jayalalithaa defeated her lone challenger Mahendran C of the CPI. This time, she faced Shimla Muthuchozhan of the DMK, a new entrant in politics.

The Election Commission came down hard on parties attempting to distribute money to voters in this election, and had seized more than Rs 1 crore in the state ahead of voting. Two constituencies, Aravakurichi and Thanjavur, will vote on May 23, after the Election Commission found that political parties were buying votes there.

A complete ban on alcohol in the state was a major poll plank this time, with each major political party promising prohibition if they won the election. The AIADMK also promised a phasing out of alcohol being sold in the state. Analysts also said the December 2015 floods would be an issue in the election.
