Kerry pulled Jim Leher's questions from his pocket.
He answered quite a few questions with facts and figures. In my estimation, there are only four possibilities:
1. The man has an incredible ability to memorize details, and is clairvoyant enough to anticipate the questions.
2. He brought notes on the points he hoped to make.
3. He knew the questions in advance.
4. He knew the questions in advance and brought notes to support his pre-planned answers.
