“Now the information is out there. How can the Republicans screw this up?”
Sadly, there’s nothing anyone can do. The agencies with authority to do something won’t do anything; they’re complicit. Mueller, McCabe, Strzok, Rosenstein, et al., could spill their guts and give every detail of every crime they’ve committed, there’s nobody to prosecute them. They’re free as birds forever.
Free because they are protected by Sessions. He’s playing the doddering clown, but none of this could have happened without Sessions decision to recuse himself, knowing that his Deputy Rosenstein would stick the knife into the President.
