The Impact of Government Participation on the Political Trust of Populist Party Supporters

Abstract Citizens are more trustful of politics if their preferred party is an electoral winner and becomes part of the government. However, there remains the question of whether this positive effect of joining the government also holds for supporters of populist parties. Populists show low levels of political trust, as they strongly criticize the political elite. This study argues that voters of populist parties perceive the political system as more responsive to their concerns when their preferred party becomes part of the government and so they become more trustful of politics. Drawing on the case of Austria, the analyses demonstrate that political trust among populist party voters is higher when their party is in government. In contrast, non-populist voters' level of political trust is more stable, even when their party is not in government.
