If you missed the forum hosted by Rick Warren with the presidential candidates this site has video and a link to the full transcript.
Of most interest to me was how the candidates would respond on the issue of abortion. Warren asked both candidates when a baby gets human rights. McCain answered “at conception,” and Obama said “answering that question is above my pay-grade.” If that doesn’t sum up the difference between these two men on the abortion question, then I don’t know what does. (Part 4 of the video link–3 minutes into it)
You can get a pretty good overview of it here.
