The last election in my country was 4 years ago, before that it was 9years ago. Both time the second turn was the “center” right versus the far right. First time I voted center without thinking about it. Second time I really didn’t want to. I looked at the polls, especially the late polls from foreign countries, and decided to vote blank. The “center” right won, but it was close. They didn’t learn the lesson at all. I hate them, but it still is way better than with the far right. I don’t know what comes next.
You did everything you could. Just keep doing that.
