No, Trump's problem is not his staff, or even that he “doesn’t have control” over his reality.
His reelection problems all spring from the fact that he was (1) elected accidentally, and (2) elected as a “minority president”, which he still is.
Donald Trump won in 2016 because his particular schtick appealed to a small bunch of voters who were annoyed that the smart people who were running the country and making the country the way it was were people they didn’t particularly like.
And, of course, these voters were able to prevail because of America’s stupid "Electoral College" system of electing presidents (which should have been eliminated long ago, but don’t get me started on things we need to do to make this a “more perfect union”) allows a minority group of quasi-crazies who don’t want the same things the rest of us do, if situated in just the right states, to get their way.
But one problem with this is, the quasi-crazies themselves have no idea of how to run a country, which means that nor will their candidate, and also, that their candidate will likely win with smoke-and-mirrors, and smoke-and-mirrors will fail when it comes to actually governance when real problems arise, such as having a heaven-sent prophet (in the person of a kneeling football player, warning that Black Lives Do Matter) ignored for several years, and a predictable global pandemic not being handled the way it should be, and early enough to do some good, the failing of which naturally causes the economy to collapse.
(Yes, Donald Trump was way too showbiz to comprehend what was being asked of him, but maybe it really wasn’t his fault! Maybe the fault was with America not taking enough care to avoid electing a natural-born loser — after all, Trump didn't elect himself!)
It’s not that Trump has lost his magic touch, it’s that magic is all illusion, and real crises are not fixed by smoke-and-mirror illusions, which is all Trump has in his toolbox. (He's really what we call a "one-trick pony".)
And as for Newt Gingrich?
“I think it took several months to realize that all the tools that worked brilliantly for four years were not in tune with where the country was,” Gingrich said.
No one should forget that Gingrich was the guy who started digging the hole we find ourselves in today, and the fact that he probably doesn’t realize that is reflected in the fact that he really thinks that Trump’s tools "worked brilliantly for four years”.
The voters who elected Trump, and especially those who eventually came to believe in him, expected him to eventually pay off with something good, but what he ended up delivering turned out to be a huge disappointment, and too late for any of his magic to turn around.
It’s funny watching a discussion amongst his Republican goons about what Trump can do to pull himself out of his nosedive, when the answer seems to be obvious:
(Or so I hope, along with just about everyone else on the planet.)
