No idea. They can go "all-in" and prove Ford a liar (thus proving the D's have been unethical in this ordeal), or make a clear statement against sexual assault in some palpable manner (not saying they have to nix BK's confirmation).
imo
mitchell’s questioning of ford was all anyone R or D wanted to see of ford
(ford would not survive nor would she want to participate in the cognitive interview mitchell laid groundwork for)
the clear statement against sexual assault R’s need goes thru flake(w/o appearing weak flake did it)
we have the fbi now involved
at the behest of a retiring senator
the D’s get their afternoon talking point FBI investigation
the scope of said investigation
has been set by potus(who will take the hit giving zero F’s) taking the fbi off the hook
potus gets his nominee
Kav gets his job
