I had to miss several of the past televised Dems presidential debates, though I read the post-mortems on them on blogs afterwards just to learn that the MSM is still not serious about doing their job. Thus, today's radio debate on NPR was quite refreshing - they had more-or-less equal time for each of them, and sufficient time for them to develop their ideas beyond the sound-bites. The questions, while not as good as they should have been, were miles ahead of the stuff CNN, for instance, decided to ask.
You can listen to the podcast of the entire debate here.
Here are some of the early summaries:
