Maybe you have seen the announcement from The Commission on Presidential Debates today:
"The Commission on Presidential Debates sponsors televised debates for the benefit of the American electorate. Last night’s debate made clear that additional structure should be added to the format of the remaining debates to ensure a more orderly discussion of the issues. The CPD will be carefully considering the changes that it will adopt and will announce those measures shortly. The Commission is grateful to Chris Wallace for the professionalism and skill he brought to last night’s debate and intends to ensure that additional tools to maintain order are in place for the remaining debates."

Most likely the moderator will have control of the microphones, but it will be interesting to see what else they think is needed.
You might say a taser for the moderator to wield. That would keep it lively!
