I don’t think debates should have moderators at all. You should just have the candidates and let them argue with one another for 2 hours and make their case. They’re all grown ups, they’ll give each other time. Maybe you could have some referee or something who could keep track of time and let them know if someone hasn’t spoken in a while.
But as far as questions and content, I’d go no moderators. Just the candidates going back and forth.
Wolf Boitzed as a “moderator” is like having Tammy Fay Bakker as a make up consultant
I’d love to see any politian give another one the opportunity to make their case when they’re running for the same position!!
