[Platapus]

And what will the benefit of twenty two debates that twenty one won't have?

I don't think Obama is scared (although I am sure that's what Clinton wants everyone to think). I think he would rather campaign in the state than have yet another debate.

I am sure he has been advised that he can garner more support by campaigning than by a televised debate.

Is there some issue that has not been debated in the past twenty one debates that will be addressed?

We know the similarities and differences between the two candidates.
