 It's Morning Edition from NPR News. I'm Amy Martinez in Los Angeles, California. And I'm Steve Inskeep in Washington, D.C. Good morning. We have some debate prep for you this morning. It is not for the candidates who appear in a TV studio tomorrow night. It is for the rest of us to make sense of what the candidates are likely to say. We had a briefing for you yesterday on immigration, and today we have a memo on the economy. NPR Chief Economics Correspondent Scott Horsley and NPR Political Correspondent Daniel Kurtzleben are both on the line. Good morning.
