The latest public opinion poll, conducted by the Parsifal Institute in June this year, reflects Slovenia’s diverse political landscape, but also shows that the Slovenian Democratic Party (Slovenska demokratska stranka – SDS) remains in the lead. Among the voters who already know who they would vote for and who would definitely go to the polls, 39 percent of respondents would vote for the party in question.
If the elections to the National Assembly were held this Sunday, the largest share of voters – namely, 23 percent, would support the Slovenian Democratic Party (SDS), followed by the Freedom Movement (Gibanje Svoboda) with 14.2 percent and the Left party (Levica), Social Democrats (Socialni demokrati – SD) and New Slovenia party (Nova Slovenija – NSi), all with the same result of 5.3 percent each. The Democrats (Demokrati), with 4.5 percent of supporters, are just behind the top five.
The poll shows that SDS’s support is growing; in February, 19.3 percent of voters said they supported it, compared to 21.7 percent in April.
Among the undecided, the largest number of respondents do not know who they would vote for (15.4 percent), 8.2 percent would not vote, 3.6 percent would not vote for any of the parties that were mentioned as options in the poll, and 2.4 percent would vote for some other, non-specific party.
Voters who have already decided who they would vote for are even more in favour of the SDS party
If we consider only the votes of those who already know who they would vote for at the elections, SDS’s advantage is even bigger. In this case, 32.6 percent of respondents would vote for SDS, followed by the Freedom Movement (20.2 percent), the Left party (7.6 percent), SD (7.5 percent), NSi (7.5 percent), Democrats (6.4 percet), Resni.ca (4.0 percent) and Vesna (3.5 percent). Among those who would definitely go to the polls, the SDS party would also be the most likely choice (33.0 percent), followed by the Freedom Movement (19.1 percent) and NSi (6.8 percent), then the Left party (6.5 percent), SD (6.1 percent) and Democrats (5.0 percent). Furthermore, if we focus only on those who already know who they would vote for and would also definitely go to the polls, as much as 39 percent of voters would support SDS, 22.5 percent would support the Freedom Movement, 8 percent would support NSi, 7.7 percent would support the Left, 7.2 percent would support SD, and 5.9 percent would support the Democrats.
How would different demographic groups vote?
In terms of gender, the survey shows that men are more likely to support SDS (25.8 percent), while women are more likely to support the Freedom Movement (14.9 percent). Among young people aged between 18 and 34, SDS also stands out with 22.9 percent of support, and Vesna with 4.8 percent. Among those aged 55 and over, SDS is in the lead (26.7 percent), followed by the Freedom Movement (20.4 percent) and the Left party (6.5 percent). In terms of education, the SDS party has the most support among those with vocational education (33.6 percent), while the Freedom Movement dominates among those with primary school or less (16.9 percent). The Left party has the most support among those with higher education (7.8 percent).
Among the voters who already know who they would vote for and who would definitely go to the polls, SDS would receive almost 40 percent support.
The SDS party has maintained its primacy over a longer period, while support for the Freedom Movement is declining, compared to 2022. Support for the Left party and SD remains relatively stable, but does not exceed single digits among the population as a whole.
The public opinion poll was conducted between the 10th and the 12th of June 2025 via telephone and online surveying of adult citizens. It included 732 respondents, 49.8 percent of whom were women. The average age of the respondents was 51.9 years, with a standard deviation of 16.4. The highest percentage of respondents had completed primary school (33.4 percent), followed by those with a higher education degree or more (30.4 percent); 22.9 percent had a vocational education degree, and 13.3 percent had completed primary school or incomplete primary school. Just under half of the respondents come from villages or hamlets, while the other half are mostly from smaller towns. Most respondents are from the Central region of Slovenia.
