To be effective in totally defeating Trump, if it were able to do that, this tape would have to have been released like the “W” DWI arrest of 30 years prior was, on the Friday before the election, leaving no response time. I am sure Team Clinton has something set up for November 4.
But that didn't work, it failed, which is why they decided to release it just prior to the 2nd debate with a month to go until the election. That way they can hammer on it and other "shocking" (at least they are hoping people perceive then that way) comments made by Trump.
Infowars is stating that Hillary has had many "Jane Does" file false rape reports against Trump. They will be found to be false only after the election.
