Writes Gail Appel:

Only the Republicans continue to snatch defeat from the jaws of victory. This could have waited until the election is/was certified. Johnson would likely have stepped down if asked and a better alternative was queued up.  Plus, those chomping at the bit to remove him voted him in, which I never understood to begin with. Johnson hardly seemed the bulldog type who could get the job done. It would have been far wiser to fish outside the pond. The GOP is blind to its own deficiencies. They should hire a consulting firm that’s gotten Democrats elected.

See this.
