Flake has no political reason to call for an investigation. He is a lame duck. He is only thinking about his FUTURE job as a lobbyist. He screwed the D's over in committee to get Kavanaugh out to the full senate for vote.

Be patient. Waiting helps us. It secures the limp-wristed republicans votes by giving them political cover. It motivates conservatives by giving them an additional week of getting shit on by the left to enrage them. The votes to confirm are there. When it happens the left will be deflated weeks before the midterm. This will result in seats gained in the Senate.

The FBI will find nothing. Trust Wray. Before this is over the left will be SCREAMING about corruption in the FBI. This plays right into Trump's hands.

Then you get Rosenstein hauled in front of the HOUSE. He will be IMPEACHED. This keeps Trump "uninvolved". Rosenstein will resign instead of facing trial. Trump then appoints a replacement that kills Mueller's investigation. The Republican's will maintain control of the House.

Then you drop FISA, Brennan,Page,Comey, Strzok, Lerner, etc.

After the midterms you go to work on RBG with Amy Coney Barrett in the wings.

Just be patient. Timing really IS everything.
