Refusing to comment on something is also about ignoring things of no substance and not letting an opponent control the conversation. If you read "The Ass Is A Poor Receptacle For The Head: Why Democrats Suck At Communication, And How They Could Improve" by Barry Eisler, he actually talks about how traditionally Democrats fail heavily at this. They respond to every distraction their foes throw at them, no matter how nonsensical. This let's the people on the other side control where the conversation is.

Instead of responding, I would hope the Biden campaign talks about policy.

There seem to be a genre of books by Democratic party partisans which talk about how their main failure is that of communication. I personally doubt that either side really controls much; some narratives are just more convincing to certain groups than to others.
