Answer:
This will most likely be Representative
Explanation:
This is due to them having different chapters in different states. It will be significantly harder for them to get everyone's vote directly, because there would just be too many of them in different locations.
Additionally, a chapter is a segment of a larger group. Meaning that each chapter will be led by different people, so it would make sense that the leaders of each chapter will act as a representative for those within that particular segment.
I hope this makes sense :)
