Donald Trump mixed partisan politics and affairs of state to dangerous extremes.
At least during those administrations, people outside the government who worked only for the president’s political campaign weren’t organizing White House meetings where they, rather than White House staff, advised the president on official actions. There’s one other key distinction: Partisan politics interfaced with official White House policy, sometimes inappropriately, but at least the mischief waselections. The focus was not on plotting to overturn elections once they were over.
There’s a reason why in every other administration the president received advice on his official acts as president from White House staff and other federal employees. Their sworn loyalty is to the United States, and only to the United States, and they are bound by federal ethics rules and statutes designed to make sure their loyalty runs only to the United States.
