He is correct about this. President Trump has left hundreds of Obama political appointees in their jobs and did not even remove some of the most reviled like John Koskinen. He could have fired Comey early, but now is completely checkmated by the DOJ and FBI. He is letting himself be ground down and surrounded. I fear that after Alabama, there will now be a new onslaught of women put up to make accusations and then there will be hearings, etc. I think Ryan and McConnell are just waiting for the right time when they think they can impeach him. The lesson to the uppity base will be to never again challenge the Uniparty and only pick from the approved candidates.
Trump has the people he wants in those roles. Like the VA, where he put Obama’s #2 guy in charge.
