All meaningless at this point. Fact is, the Trump administration failed miserably on the personnel front. They kept thousands of Obama appointees in position after taking office. Just doesn't get any dumber than that!
Then, Trump kept all the Obama senior military who went through a filtering process to be able to stay in Obama's military. Another dumb as a stump move by Trump!!!
Trump worked hard to get things done, but in the end, he could not trust anyone but his family, and that is no way to run a government. Four years of painful lessons, and he did not work to build his own team, without using Bush and Obama resources. The kiss of death for him in my humble opinion. Had he built his own team, folks without prior Bush and Obama experience, he would have done much better.
