Ask yourself this. Why? Why did she do this?
It wasn’t to help out the GOP, or to help out Trump. It was to advance their own interests.
Perhaps they really believe the files. Perhaps they know they are fake and want to get the disinfo out there as fast as possible.
Who benefits?
Of course her intentions were nefarious. It the results that are great. This was an epic blunder, unless Feinstein thinks appointment of a Special Counsel to go after the Clinton/Obama/FBI/DoJ/CIA/ODNI/NSC/Fusion GPS conspiracy would benefit the Democratic Party. (If they could put one of their stooges in charge, it might. Trump had better not let Rosenstein pick another Hillaryite SC).
