I think they were waiting to release the Billy Bush tape till this week but the WikiLeaks stuff started coming out and they had to change the subject fast. I think they made a call to release it early and to put Trump away with the help of the media. They tried. The bimbo eruptions were all part of it too with suspicious timing.
That's been my theory also. The plan was to release the tape and stage the parade of women accusers at the end of this week to ensure maximum media coverage and leave the Trump campaign with no time to respond. As you've stated, because of Wikileaks, they were forced to play that card much earlier than planned. They've tried to revive it by recycling Miss Universe the other day, and I've seen some Hillary ads the past few days focusing on Trump's alleged mistreatment of women. Hillary has been forced to devote her time this week battling the F.B.I. I'm not sure they have anything new to use against Trump.
