Kavenaugh will be forced through
We will have to see who has the Senate and White House for the rest
That is still yet to be seen, and "forced through" is a less than accurate portrayal. All that needs to happen for Kavanaugh to be confirmed is receiving the votes required to be confirmed, and no one is forcing anyone to do that. Republicans and Democrats can vote any way they want on the confirmation.
He will receive his vote regardless of the findings of the FBI
That is why McConnell has already scheduled a vote
We already know the democrats will vote against him, so what's the purpose of the investigation? Is it really just to placate the trained seals?
