We hate hearing the same rhetoric all the time. Candidates probably hate getting the same questions all the time. So here's an idea I had that I'm throwing out into the wind for any campaign or political community to take advantage of: distributed interviews.
You set up a site for a community to suggest questions, and get a list of questions approved. Then for each city that the candidate is, a representative of the effort is picked to go interview the candidate and record it. It would be Joe Smith from Distributed Interviews. He goes and asks ten minutes worth of questions, then posts the transcript/audio back to the site. The community then comes up with followup questions, either for further clarification or for new questions, the candidate moves on to the next city, a new representative - Mary Williams from Distributed Interviews - is picked from that city to meet with the candidate for part II of the interview. The candidate has had time to think about the latest interview subjects, and the interviewing community has had the time to come up with meaningful follow-up questions.
So then by the end you have a long Charlie-Rose type interview with a good chance of real, insightful content and commentary.
If it's not already being done, feel free to point to this entry and suggest it to various campaigns.
