This sort of thing will never happen during, or following, the Biden administration. Love him or hate him, and for me it is much closer to the latter, Biden understands the need for any POTUS to populate his administration with like-minded lackeys. Trump certainly did not understand this for the first couple of years. He might now. I hope he does now; but of course it is too late.
Trump did not understand that if you populate your administration with holdovers from the old guard they will stab you in the back at every opportunity. Bush, back in 2001, also had trouble with this concept. Why is it always Republicans who fail to understand the obvious?
Anyway, Biden’s Rolodex has no such insufficiencies. And America will be just that much worse off because of it.
