It's been fantastic purely for the faithful, who are pre-sold on Trump. It's not fantastic for CNN, which has been trying to pretend its pivot to 'the center' is Serious Journalism and that this event would not be an embarrassment. Both of those objectives failed. Most people didn't watch this live, they watched the ugly highlights on Twitter. They should never have done this.
You'll see (and are already seeing) the usual Beltway wagon-circling for poor valiant Kaitlan Collins who is one of the gang - she even roused apolitical access robot Peter Baker to her defense while he was studiously ignoring this event - but make no mistake, it was a disaster for their rep.
