Political Debate Club Q's

So I run the Political Debate Club at my school and recently met a local politician who is willing to come and speak to my club. He said he could just have a general conversation, but that would require students to ask questions and I don’t trust them to do that. He also said I could email him a topic for him to talk to us about.

So, what should I ask him to talk to us about?

Running for offices
Constructing a campaign
Creating good, [buzzword] policy
