Janice,
I'm not sure whether it's a matter of cutting slack but what and how criticism is directed. Jill Biden can't be completely shielded.
Jill Biden doesn't deserve to play a scapegoat. Still, she is active in this political crisis by publicly supporting her husband's decision and advocating a position affecting America's future.
The criticism must be her opinion, not a personal attack.
Biden must not make his wife a scapegoat.
Best.
