I didn't get to see the thing live and have only heard parts of it since. It seems to me that this is the best format yet. It makes perfect sense that states attorneys general (charged with dealing with state/federal interactions) get to interrogate the candidates. It's certainly better than listening to self important boneheads like Scott Pelley try to score points with their buddies on the cocktail party circuit by endlessly trying to trip up a candidate and "make" news.
The other thing that made the format good was the determination to prevent the one-on-one candidate fights that have characterized previous debates.
What we ended up with was good information on each of the candidates rather than another round of ammunition for the Democrats.
I do not like Huckabee at all but I am forced to give credit where it's due and this was a very, very good forum for providing useful information to the voters.
I do not have high hopes for Trump's upcoming debate.
BTW, there is at least one site that has a complete streaming copy of the forum if you want to go back and analyze the thing. It can be found
here.
