Organizing a presidential election campaign and stimulating voters to vote for a particular candidate is a great skill. Productive marketing and the most positive image in the media are the two most important factors that need to be worked on in order to obtain the best possible result in the presidential elections. The campaigns of Stjepan Mesić, Barack Obama and Donald Trump are some examples of successful political marketing, but the use of populism should be given great importance in these campaigns. Populism is one of the most commonly used communication styles in presidential campaigns around the world, including Croatia. The main aspects of populist communication are: appealing to the people, simple messages, opposition to elites. Many politicians believe that by using populism they can get a better result in the elections, and as an example we took the presidential elections in Croatia in 2019, where populism was very pronounced. Using sources from professional literature, it is established that the three most popular candidates from those elections, Zoran Milanović, Kolinda Grabar Kitarović and Miroslav Škoro, used populism, each in their own way and to a certain extent. Škoro used populism the most, followed by Grabar Kitarović, and then Milanović. It is unquestionable that Grabar Kitarović and Škoro achieved an impressive result in the first round of the presidential elections, regardless of the fact that Grabar Kitarović did not win in the second round of those elections. Milanović was the final winner of those elections, and he built his campaign on opposition to the „HDZ political elite“, which he believes has completely set Croatia back and that he is the savior who will put an end to that elite. From this paper, we can conclude that the use of populism can greatly affect the election results of candidates who use it.
