They were sick of the politics bullshit and decided to troll the elections in their small town. His pseudonim was Beli Preletacevic (translates to something like White Flipflopper). And they just went with most bizarre promises. He was also saying he will steal but also give to the people, he will take bribes... and they won over 30% in their town (second best)
Presidential elections were next year so they just run with it. Not sure what would happen if that was today with all this Tiktok, instagram shorts and trends, it would probably be even crazier. But getting 3 place in a presidential race while driving around with your friends in a Golf 2 around the country with budget of few 1000e was pretty crazy and showed how sick people are of politicians.
