Alex Chediak has more information on the Obama/McCain joint appearance at Saddleback:
The folks at Saddleback have set-up a website describing the August 16 joint appearance between Senators Barack Obama and John McCain (moderated by Pastor Rick Warren). Ticketing information will be available August 1st.This historic forum will be the only joint event for the two, and the last public appearance for either candidate prior to the two-week hiatus during each party’s national convention.
Due to Secret Service mandate, tickets will be required for the event in the main auditorium, but the program will be broadcast live in multiple venues on the Saddleback campus, as well as on several national broadcast networks and online. It will also be streamed live on www.SaddlebackCivilForum.com.
Update: Ross Douthat has a post on Obama and Evangelicals. He concludes it by saying: "Obama's performance at Saddleback (and McCain's) will probably be at least mildly important in determining how those undecided evangelicals cast their votes."
