In a normal world, when you know bad news is a coming you leak out some of the details so as to blunt the impact. But cannot do that because the details probably involve the Clinton foundation.
The preemptive partial leak/release was another patented Clintonian tactic of the 1990s. As you point out, the Ds may not risk that. Brazening things out was another patented Clintonian tactic, and more in line with
The SHREW's elitist arrogant personality and character.
That said, were the D Party really interested in cleaning house, they'd release everything relevant - to the relevant law enforcement agency and the media and purge the Hades out of the operatives who did this @#$%.
NOT. GOING. TO. HAPPEN.
