 ahead of tonight's historic presidential debate in Atlanta. Talking to sources right inside the top ranks of these campaigns, it's fascinating to me. They really do think this debate matters, that a lot of people have been at school, they've been dealing with their families and friends, maybe they're paying attention to Taylor Swift's Heiress Tour, whatever they're doing, now they're tuning in. CBS's Robert Costa in Atlanta. The CNN-hosted debate begins at 9 p.m. Eastern time. In Israel, hostage families take their anger with their leaders to the streets.
