This Saturday certainly could generate some interesting soundbites--it's the John McCain/Barack Obama dual event at the Saddleback megachurch in Lake Forest, California.

U.S. presidential rivals Barack Obama and John McCain target religious voters on Saturday when as guests of one of America's foremost evangelists they discuss faith in public life, AIDS, the environment and other issues...

The candidates won't debate each other at the Civil Forum which will be moderated by mega-pastor Rick Warren at his Saddleback Church in Lake Forest, California. He will interview each in turn, although they are expected to share the stage together briefly.

One of the hotter topics, one would think, would be abortion, particularly given McCain's recent hints that a pro-choice VP is not out of the question and recent noise about Obama's pro-choice past. But with the warm-and-fuzzy nature of this event--together with pastor Rick Warren's recent moves to "embrace a broader range of biblical concerns such as poverty and climate change, moving beyond though not excluding culture issues such as abortion"--it wouldn't be surprising to see the more challenging questions stay firmly in the holster. Stay tuned.
