I’m not sure that the   R’s don’t want a sh!tsh@w. As seen in the Kavanaugh hearings - this ccan also be good for R’s.  Logic would suggest that D’s should back off this time round but I’m not sure they can for two reasons: 1)their base demands blood so-to-speak (same with POTUS impeachment - bad idea but they have promised base) 2)I’m not sure they have any other plays in playbook - They are so used to R’s laying down and rolling in any fight they’ve never developed a more long range tactical plan
