I think letting this go before the FBI has been the plan all along.
The FBI will not only interview Kavanaugh, Judge, and others who were there, but they will also interview all of the accusers that have come forward (not just Ford).
Remember what happens when you lie to the FBI? I think that they already have figured out these stories, and are letting these democrat plants (accusers) walk right into a trap. The democrats will be hugely discredited, and these women will all serve prison sentences.
This will be a HUGE DETERRENT for any future women that the democrats try to pay off to falsely come forward. Additionally it will be very damaging to the democrats for the midterm elections as it will show just how disgusting they are in that they are willing to completely destroy a man's life and hurt his children and family, just so they can have power.
