Interview suggestions (please add more to the comments if you have other ideas)
Invite the State Democratic Party Chairs to have an interview where they can talk about how their state works in terms of the delegate process. Send out the invites in the order that the states have their contests, so Iowa and then New Hampshire, etc. You don't have to record them in that order, just invite them in that order. Wikipedia has the breakdown of the dates. This will give them a chance to invite people to get involved, and if they refuse because you're a Bernie channel we'll know that we need to find someone else. Also post whether they accept your invitations.
