As of 2024, this remains the last Polish presidential election won by a non PiS-aligned candidate.
Background
The 2010 presidential election was expected to be a rematch of the 2005 election between Lech Kaczyński and Donald Tusk. Since the last presidential election, Polish politics had become centered around the rivalry between Law and Justice and the Civic Platform. President Kaczyński and Prime Minister Tusk were constantly battling each other over who should represent Poland on the international stage.[2] Tusk was leading Kaczyński in all the opinion polling (as he did in 2005 before he ultimately lost) and the election was expected to be a dirty one. However, this rematch never came to be. Donald Tusk announced in January 2010 that he will not run for President because he wants to remain Prime Minister.[3] Lech Kaczyński was set to declare his candidacy for re-election on 23 May but he died on 10 April in the Smolensk air disaster.[4]
After Donald Tusk declined to run for president, the Civic Platform organized a presidential primary. The primary was won by Bronisław Komorowski who defeated Radosław Sikorski receiving 68.5% of the vote to Sikorski's 31.5%.[5] Bronisław Komorowski consistently lead Lech Kaczyński by double digits in the first round and by a 2-to-1 margin in the second round. No other candidate registered support in the double digits.[6]
After President Lech Kaczyński's death in a plane crash on 10 April 2010, the Constitution required the Marshal of the Sejm to declare the date within two weeks, with the election to take place on a weekend within the following 60 days, i.e. 20 June at the latest. On 21 April, the Marshal, Bronisław Komorowski, announced the election date as 20 June 2010.[7] Candidates were required to register by 26 April 2010 (with 1,000 signatures of voters in support) and submit 100,000 signatures by 6 May 2010.[8]
Originally, Kaczyński was up for re-election between 19 September and 3 October; the exact date would have been announced between 23 May and 23 June, before the end of his first five-year term of office.[9]
Two candidates for the election died in the crash. Incumbent Lech Kaczyński was nominated as the Law and Justice party candidate (he had yet to accept the nomination, but it was widely believed that he would do so), and Jerzy Szmajdziński was to have run for the Democratic Left Alliance.[10]Jarosław Kaczyński ran for president as the replacement for his deceased twin brother.[11] Jerzy Szmajdziński's replacement was Grzegorz Napieralski.[12]
In total, 23 candidates registered with the Polish National Electoral Commission on, or just following, the 26 April deadline. 17 of the 23 candidacies were accepted by the commission, whilst the remaining 6 were rejected because they had not gathered the required 1000 signatures.
Only ten candidates collected the required 100,000 signatures and were eligible to run for president.[13]
Bronisław Komorowski's campaign slogan was "Unity builds" (Zgoda buduje) and his strategy was to portray himself as an independent politician ready to work with everyone to fix the nation's problems. He pledged to work closely with the government of Prime Minister Donald Tusk to adopt the euro in about five years, end the unpopular military mission in Afghanistan and promote pro-market reforms.[19]
Jarosław Kaczyński's campaign slogan was "Poland is the most important" (Polska jest najważniejsza) and he aimed to soften his own image and present himself as someone ready for compromise. He praised his late twin brother's legacy and promised to continue his policies as President. He made it a priority to fight crime and corruption, scale back market reforms to preserve a strong welfare state and promote Roman Catholic values [19]
Soon after exit polls were released in the second round, Jarosław Kaczyński conceded that he had been defeated. Bronisław Komorowski appeared to tentatively claim victory, stating: "Tonight we will open a small bottle of champagne and tomorrow we will open a big bottle."[48] The exit polls put Komorowski ahead of Kaczyński by 53% to 47%.[49] On the following day, Komorowski was declared the winner of the election.[50] The final result put Komorowski with 53.01% of the vote, and Kaczyński with 46.99%.[47]
Komorowski's win resulted in Civic Platform holding both the Presidency and the government (under Prime Minister Donald Tusk).[51] Correspondents in US and British business newspapers suggested that Komorowski's win would mean closer engagement with the European Union,[52] and such domestic economic reforms as deficit reduction.[53]
