OK it's not university debating, and some people may say its not debating at all, but possibly the most watched "debates" around the world are those which occur every 4 years between the candidates for the US presidency.
The second presidential debate is on tonight at Belmont University. It is a "town hall" style "debate" where questions will come from the audience and on-line viewers. Each candidate will have two minutes to respond to each question.
The moderator is Tom Brokaw and as the name calling has started in the past couple of days he might have a tough job (probably not but you can hope).
The third and final debate is on the 15th October.
