 ABC News, I'm Sherry Preston. The first 2024 presidential debate is set for tonight in Atlanta. ABC's Stephen Portnoy has more on some of the rules. The two lecterns are spaced just eight feet apart. The 90-minute debate will feature two commercial breaks. No staffers will be allowed on stage. A two-minute answer to each question will be followed by a one-minute rebuttal and then a response to that rebuttal. CNN has agreed to mute the microphone of the candidate who isn't recognized to speak.
