The article analyzes affective polarization in Lithuania among voters of different parties, aiming to determine what drives their political antagonism: partisanship or specific issue-based attitudes, such as support for Ukraine in its fight against Russia, views on same-sex marriage, support for the European Union, evaluations of the Soviet period, and attitudes toward COVID-19 vaccines. The study employs a new tool in Lithuanian political science – a conjoint experiment. The results show that in some cases partisanship (specifically, support for the party “Nemuno Aušra”) acts as a factor that divides voters, even when the influence of issue-based factors is eliminated. Supporters of different parties are antagonized by different issue positions; however, on one issue the attitudes of supporters of all examined parties coincide – those who support Ukraine are consistently evaluated much more positively than those who do not.
