 Donald Trump arriving a short time ago at Hartsfield Jackson Airport. No mock debates for him, but some policy sessions with advisers behind the scenes. Trump has said he's been preparing his whole life for this. Tonight, we will break it all down, including where this race stands going into tonight. Several new national polls out in the last 24 hours where they show this race right now and why each candidate needs a very strong showing tonight to move the needle, given how close this race is. ABC's Rachel Scott leading us off tonight at the debate site. She's in Atlanta for us.
