If you didn't see the discussion Rick Warren had at Saddleback church last night with Barack Obama and John McCain, this 3-minute excerpt video does a good job of showing one significant difference between the two candidates. Helpful hints: Notice Obama's nonanswer to the question, "Have you ever voted to limit . . . " [the accurate answer would have been "No"], and notice McCain's answer to the question that is the title of this post.
