On Wednesday (February 5th) afternoon, a resolution by the Sejm Speaker Elżbieta Witek scheduling presidential election on May 10 was published in the Journal of Laws. Thereby, the presidential campaign was officially commenced. According to polls, the incumbent president Andrzej Duda, backed by his former party - the ruling Law and Justice (PiS), stands the best chance to win and be re-elected. His opponents, however, claim that in politics one can never be sure of anything, and pledge to fight to win over the hearts of voters.
