I think an investigation leading to major arrests just before the next election will throw the Demoncrats into total confusion.  If the take down includes corrupt politicians currently in office it could flip the house back and give Trump the power to go full steam ahead for his second term.  This has nothing to do with declassification.  They can do that immediately.  Once the public digests what happened, a SC would be the logical thing to do culminating with arrests a few months before the 2020 election.  The country would be awake to the crimes and incentivized to vote.  Trump and Republicans win big, Dems lose to where it collapses the entire party.
