As I’ve said before, if that comes to pass, it will be a very tightly constrained format with little actual “debate”. There will only be one.
If it comes down to that, Cain would earn a great deal of cred if he publicly called on Obama to have a real debate, without so many of the silly, schoolkid crap, like Romney whining that Perry wouldn’t let him talk, or Bachmann saying the moderator’s name over and over.
