Presidential elections were held in Finland in January and February 2012. The first round took place on 22 January 2012 with advance voting between 11 and 17 January. Since no candidate received a majority of the vote, a second round was held on 5 February, with advance voting between 25 and 31 January. Sauli Niinistö was elected the President of Finland for a term from 1 March 2012 until 1 March 2018.

All eight political parties represented in Parliament nominated a candidate during the latter half of 2011. Incumbent President Tarja Halonen was ineligible for re-election, having served the maximum two terms.

As no candidate received a majority of votes in the first round, a runoff election was held between the top two candidates, Sauli Niinistö of the National Coalition Party (who had received 37% of the first-round vote), and Pekka Haavisto of the Green League (19%). Niinistö led opinion polls prior to the elections, while Haavisto was neck-and-neck with Paavo Väyrynen of the Centre Party competing for second place, ultimately defeating Väyrynen by a margin of 1.3 percentage points (about 37,000 votes). Niinistö won the second round with 63% of the vote, while Haavisto received 37% of the vote.

The elections marked an end to an era of Social Democratic presidents. The Social Democrats had held the office for a continuous period of 30 years. It was also the first time that a Green League candidate was on the runoff ballot.

Power of the president The president's powers were curtailed in the constitutional reform in 2000, and yet further in 2012. Currently the President leads the Finnish foreign policy together with the cabinet. EU affairs, however, fall to the Prime Minister's authority. The President has little domestic power. He or she can dissolve the parliament, but only at the Prime Minister's request. The President can choose not to ratify a bill, but this only returns it to parliament, which must then approve the bill again in order for it to become a law without the President's signature. The President's power to appoint officials has been reduced, but he or she still appoints all military officers as well as judges. The President is the Commander-in-Chief of the Finnish Defence Forces. The President also has the power to pardon anyone convicted of a crime.

With the curtailment of the President's formal powers, many analysts have emphasized the President's position as a leader of values.

Candidates All eight parties represented in the Parliament nominated a candidate. The nomination was unanimous in seven parties, while the Social Democratic Party's candidate was decided in a primary, which was won by Paavo Lipponen with 67% of the votes defeating Tuula Haatainen, who got 22% of the votes, and Ilkka Kantola who received 11% of the votes. Each candidate was given a number from 2 to 9 – voting took place by writing the candidate's number on the ballot paper.

Constituency associations for independents or parties not represented in the Parliament must gather 20,000 signatures from eligible voters in order to participate in the election. In 2012, no such associations participated. Pekka Hallberg, the President of the Supreme Administrative Court, considered running as a non-partisan candidate, but eventually withdrew.

Campaign

According to political analysts Salla Laaksonen and Kimmo Elo, the main dividing line between the presidential candidates in this election is not the traditional division over ideology, but instead voters are placing more stress on a candidate's views on the EU and social issues.

Professor Leif Åberg has described the campaign as "relatively civil," but there have been a few accusations of negative campaigning. Some of Pekka Haavisto's supporters felt offended over a television advert by the Paavo Väyrynen campaign which says that "a house needs a master and a mistress." Haavisto's supporters interpreted this as a taunt on Haavisto's relationship status (Haavisto lives in a registered partnership with another man). Väyrynen responded by rejecting this interpretation and in turn accused Haavisto's supporters of deliberately twisting his words. The satirical television programme YleLeaks mocked the election in mid-December 2011. Niinistö's wife, Jenni Haukio, complained with a letter to YLE'''s A Studio saying that she was a private person. An A-Studio political reporter also criticised Iltalehti of news in favour of Sauli Niinistö.Väärin naurettu yle 13 December 2011 Foreign Minister Erkki Tuomioja accused editor A.-P. Pietilä of undervaluing Haavisto's abilities in foreign policy based on his companion; Pietilä wrote, citing an unnamed civil servant, that Haavisto's election as president might complicate Finland's bid for being elected as a non-permanent member in the UN Security Council as several countries where homosexuality is outlawed might oppose the bid in this scenario.

Funding The parties budgeted less money for their campaigns than during the last presidential election in 2006. This was in part due to the 2008 financial crisis and in part due to scandals involving campaign funding over the last few years. According to initial estimates, the four largest parties planned to spend less than 3 million euros combined.

Of the second round candidates, Niinistö's budget was 1.2 million euros and Haavisto's budget was 725,000 euros.

Debates

First round MTV3 organised a debate with all eight candidates on 14 December. When discussing the European sovereign debt crisis six of the candidates believed in the survival of the euro, while Soini and Väyrynen believed that the eurozone would dissolve in one way or another. Väyrynen accused Lipponen and Niinistö of misleading the parliament, when Finland joined the common currency in the early years of the 2000s (when Lipponen and Niinistö were the leading figures of the government). Soini was the only candidate to answer that as president he would address the issue of returning Finnish Karelia to Finland in discussions with the Russian government. All candidates were opposed to Finland joining NATO, although for slightly differing reasons. Soini and Essayah underlined the importance of credible national defence, expressing concerns about defence cuts. Lipponen too was concerned about NATO membership's effects on the Defence Forces. Niinistö said that increasing security cooperation within the EU might make joining the NATO unnecessary in the long run. Biaudet stressed European defence as well, while Arhinmäki wanted to strengthen the role of the UN. EU issues were topmost in the YLE debate on 15 December as well.
