[EX Q]: Question: Which of the two political parties in the 2008 Serbian presidential elections has won the most presidential elections? Passage:Held against the backdrop of the 2008 Serbian presidential elections contested between incumbent Boris Tadic from the ruling center-left Democratic Party (DS) and challenger Tomislav Nikolic from the opposition right-wing Serbian Radical Party (SRS) as well as speculation that Albanians from Serbia's province of Kosovo were in the final stages of coordination with the United States to unilaterally declare independence, the festival received plenty of attention both in the Serbian and foreign press. Political angles and overtones dominated foreign press reports such as the one by in center-left Liberation who, after giving praise to the festival for celebrating auteur cinema, wondered if the fact that festival's jury is headed by Peter Handke whom she described as someone "who still smelled of sulfur after being at Milosevic's funeral and who wrote about Serbs in panegyric form due to seeing them unjustly accused of all evils" also mean that Kusturica adheres to these ideas. She answers her own question by saying that, like Handke, Kusturica also believes western Europeans have demonized Serbs and Serbia, but that the Serbian director supports center-left candidate Tadic at the presidential elections.
