Elections are routinely investigated with a focus on the way in which winners or losers of the elections are different in their attitudes towards the political system. There is no previous research on the general impact of participation in the electoral process on support for the political system. In this study, we hypothesize – based on the procedural fairness theory – that participating in elections raises the voter’s political trust, irrespective of the result of the party s/he voted for. Furthermore, we expect this impact to be largest for voters with the lowest level of internal political efficacy. These expectations are investigated using the Belgian election panel (2009-2014) study, observing political trust before and after the elections in two consecutive electoral cycles. The results provide support for all proposed hypotheses, highlighting the importance of general participation in elections for democratic legitimacy.
