Professor Niklas Bolin argues that the Sweden Democrats’ most consequential transformation is institutional normalization rather than ideological moderation. As Sweden approaches the September 13 election, SD has become deeply integrated into the political mainstream while retaining a resilient populist configuration centered on people-centrism, anti-elitism, popular sovereignty, and antagonism. Professor Bolin stresses that “institutional normalization does not necessarily mean ideological moderation,” even as SD has gained substantial influence through the Tidö Agreement. He also notes that the party has won “an important ideological battle” as restrictive migration positions have become mainstream. Yet normalization creates a paradox: the more successful SD becomes, the more it becomes part of the establishment it has long defined itself against.
Interview by Selcuk Gultasli
Five days before Sweden’s September 13 parliamentary election, the country enters the final stretch of the campaign with an unusually fluid electoral landscape. The latest Novus/TV4 poll places the opposition at 50.3 percent and the Tidö parties at 47.9 percent, with the gap still within the statistical margin of error. The Liberals (L) have climbed to 4.3 percent—just above the parliamentary threshold—while other recent polls still place them below it, making their survival one of the most consequential variables in government formation. At the same time, the Social Democrats (S) remain the largest party overall, while the Sweden Democrats (SD) continue to challenge or surpass the Moderates (M) for leadership of the Swedish right.
In this interview with the European Center for Populism Studies (ECPS), Professor Niklas Bolin, Professor of Political Science at Mid Sweden University, argues that the most significant transformation of the Sweden Democrats is not necessarily ideological moderation but institutional normalization. As he puts it, “Institutional normalization does not necessarily mean ideological moderation.” A party, he stresses, can become “more professional, more accepted by the other parties, and more integrated into the political mainstream without changing its ideological worldview.”
This distinction is crucial for understanding SD’s trajectory. The party has moved from pariah status to substantial policy influence through the Tidö Agreement, while its core populist configuration—people-centrism, anti-elitism, popular sovereignty, and antagonism—has remained resilient. Professor Bolin therefore cautions that the party’s normalization and growing political influence should not automatically be interpreted as evidence that it has “become less populist” or that “its ideology has changed to the same degree.”
The interview also explores how SD’s success has reshaped the wider party system. Professor Bolin notes that Swedish migration policy has “clearly moved in a more restrictive direction” and that positions considered controversial 10 or 15 years ago are “today almost political mainstream.” In that sense, he argues, “the Sweden Democrats won an important ideological battle.” Yet this mainstreaming produces a paradox: when other parties adopt similar positions, they both legitimize SD and reduce the salience of issues the party once dominated electorally.
Bolin further suggests that SD’s growing success creates a tension between outsider identity and establishment power. The party has benefited from substantial influence without formal governmental responsibility, but “the more successful the party becomes, the more it becomes part of the establishment itself.”
Against this backdrop, the 2026 election is about more than which bloc wins. It tests whether Sweden is consolidating a new party system in which the radical right has not merely entered the mainstream, but helped redefine it.
