What are the possible implications if the Mueller report completed in may 2018?

What events since would be viewed differently if we knew this information?

I know the mid terms were affected and they would not have been if the report was released before hand.

So why withhold it? If the redacted page D5 contains damming info. Why was the release withheld.

I refuse to accept incompetence or things take time.

Something major has happened since may 2018 and yesterday.
