Then it is probably the elections to European Parliament you’re interested in. In such case things are somewhat different.
Elections to European Parliament have to use proportional representation, as opposed to majoritarian system used in USA (and, since most of participants in this forum are from USA, some advice might have to be adapted). According to
2019 European Parliament election in Croatia - Wikipedia (Croatian Wikipedia seems to have a worse article), you will get to vote for one party list and for some of the individual candidates in that list.
What does that change?
First, when elections use proportional representation, you get not a two-party system, but a multi-party system. That, in turn, means that votes for “minor” parties are not necessarily wasted.
Second, when you get to choose candidates in party lists, you get more chances for “tactical voting”. For example, you can vote for a party list and a specific candidate in that list specifically to show support, to encourage him, to encourage the party to move closer to his position.
and i dont have interest in politic
That, specifically, is what the Church wants to discourage. As a citizen of a democratic state you are partially responsible for your government.
So, what can you do (if not for this election then, at least, for another)?
Read about the parties (at least the main ones). What ideologies they represent? What issues they find important? What have they done when they got power? (Lying politicians haven’t been unheard of.) What disagreements they have?
And read about Catholic Social Doctrine. For example, the Compendium of the social Doctrine of the Church (

Then think how they match.
