 President Biden will enter from the right side of your screen. President Trump will enter from the left side of your screen. The podiums are eight feet apart. Directly across from them, the moderators, CNN's Jake Tapper and Dana Bash. Now, a reminder, this is a television studio. There's no audience. Candidates will have two minutes to answer questions and one minute for responses and rebuttals. At the moderator's discretion, there may be an additional minute for follow-ups, clarifications, or responses. So how does a candidate know how much time is left to speak?
