What Is a Conditional Effect in Political Ads?

In the Netherlands, there are 37 different parties competing in an election. This means that if you target people with different ads from different political parties, there are different circumstances you have to account for. And also we see for some evidence in research that some people are more likely to be affected by political ads than others. So it's important to look at who are the people who are morelikely to be influenced by political ads. I think this is an important question for future research, for instance.
