 means voters will be paying attention to the substance of the debate, but also to the tone. I'm Matt Piper. The big changes, no live audience and muted mics, ensuring the candidate can speak uninterrupted during his allotted time. There will also be a simple setup with only a pen, paper and water allowed on stage. Pre-written notes are not allowed, nor is sitting. And during the two commercials over the hour and a half debate, the candidates cannot meet on the sidelines with their advisors.
