TIME managing editor Rick Stengel and PBS NewsHour anchor Judy Woodruff question McCain, Obama during a national service forum Thursday at Columbia University in New York City.

McCain: Jokes about his age, praises Ted Kennedy, says he thinks the draft “was most unfair” because “the wealthiest found ways to avoid” it.
