I can't imagine the frustration level involved in relying on a middle-man to communicate. It's like the kids' game "Telephone:" anytime we whisper in someone's ear, our message always ends up changed somehow. And yet political candidates and office-holders have to rely almost exclusively on middle-men to tell their stories to voters. In the past, it's simply been impossible to communicate directly to everyone, without having a reporter or an editor in-between.
That's why I think politicians stand to benefit the most from podcasting, if they do it right. If a politician is forward-thinking enough to talk honestly and interactively with voters, a podcast is a great opportunity to cut out the middle-man. Imagine, after years of relying on a messenger to communicate, being able to talk directly to the people you want to speak to!
Podcasting is really just an extension of the traditional political commercial -- but without the time constraints. What would that kind of candidate site look like? How about this?
