folks gonna miss this from just the headline, but someone should point it out: the lack of live fact-checking by the moderators *was part of the agreement* by the campaigns. It's not just that CNN /didn't/ live fact check it. It's that they /weren't allowed to/.
In debates of yesteryear, it was expected that candidates would largely stick to truth, even if they often didn’t. That is not true in any way shape or form anymore.
