The turnout was higher, but the percentages were not that different from 2015, the only difference is that the anti-Duda campaign was more intense this time.
2015 result: Duda (51,5%) Komorowski (48,5%)
2020 result: Duda (51.08%) Trzaskowski (48.92%)

Right now we, sadly, have a socialist/communist government in charge but the voter registry and the ID laws work terrifically.
