Does far-right legislative entry affect minority candidate diversity?

Using a regression discontinuity design, we examine the causal impact of far-right parties’ first-time entry into Swedish municipal politics on the inclusion of candidates from groups frequently targeted by their rhetoric, namely immigrants and sexual minorities. Leveraging validated candidate data, we find that far-right entry has a negative effect on the share of immigrant candidates within mainstream parties. However, this average effect masks important differences across parties. Left-wing parties respond by increasing immigrant recruitment, resulting in a net increase in immigrant representation on ballots. In contrast, right-wing parties reduce their share of immigrant candidates, largely due to limited recruitment of new candidates. These findings highlight how far-right legislative presence shapes the recruitment and retention of minority candidates in democratic politics.
