The Utah Senate has a podcast called Senate Radio, a podcast featuring Utah Senators talking about their bills and ideas. Obviously, the interviewer is a friendly, but there's still some good value here. I like that it's a real podcast--you can subscribe with iTunes or whatever podcatcher you use and have it show up on your iPod if that's what you want. Otherwise, you just go to the site and listen there.
I'd like a list of the most recent shows to show up on the page (you can click on "Posts" on the embedded player and get that information). The production values could also be upgraded a little. Just getting into a room with less echo would help.
Still, this is a great example of politicians disintermediating the media by speaking directly to voters.
