Targeting Campaigns on More Contested Issues, Like Abortion?

We saw some evidence of that that these parties focusing on their own issues, but they also focus on different issues. So here we saw some diversification of the campaign. The second thing we wanted to study is do political parties focusing on these more contested or rich issues, such as abortion or gun control, and then see if they target more on these specific issues. And we found some mixed evidence for that as well. But as a function, I want to study more in the future to which extend these more contested issues are more likely to be used during election campaign.
