Why would you do that? You don't own an IPod.
Because ANY computer (Mac or PC) can use the application. AND, there are Thousands of podcasts on a wide variety of topics - education, leisure, exercise (both audio and video), religions, and, yes - politics.
I have several podcasts that I subscribe to - though they are delivered without any more effort, I still have choices - I can listen to them, download them to an mp3 player (NOT just an IPod), or, if the topic isn't that interesting to me, I can delete them.
One such pocasts that I'm listening to right now is Newt Gingrich's speech at this year's CPAC (Conservative Political Action Committee). I never voted for Gingrich, don't plan to, but he is a remarkably clear and compelling speaker. He lays out issues in understandable language, and speaks both knowledgeably and straightforwardly.
Here's the podcast.
