The Dems are moving to impeachment to drown out the release of the IG report, unredacted documents from the WH, and the protracted Durham investigation that will be done quietly.
Re the IG report: IMO we are going to be disappointed with the results. It will deal mainly with reforms to the FISA process and mistakes and abuses. There will be few criminal referrals. This in-house investigation will protect the institution in much the same way that the Hillary email IG report did.
Your points are what I am worried about too. I hope you and I are wrong.
