An article in the Federalist summarized it this way:
"The FBI’s warning and the federal government’s efforts to prompt the private censorship of speech, however, are not the heart of the scandal. Worse still is that the New York Post story was true, the computer files were not hacked, and the October surprise was not Russian disinformation but a legitimate and important news report establishing Joe Biden lied to the American public about his knowledge of his son’s business dealings and was also implicated in a pay-to-play scandal. And the FBI knew those facts for nearly one year, having seized the Hunter Biden laptop from the computer repair shop owner in December of 2019."

If Trump was effective and had competent people in place, he should have known about the laptop in early 2020. The DOJ and FBI are under his direction as President. Because he has no loyalty to anyone, particularly lawyers, he is unable to hire smart, tough, legal risk takers. During his whole Presidency the intelligence community that was nominally working for him was dishonestly working against him. He is a loose cannon who either inadvertently or intentionally undermines his own lawyers. If he can't get good lawyers for the intelligence agencies ---and the many other govt departments, he is necessarily ineffective. Comparing him to DeSantis, who is focused and disciplined -- there is no comparison.
Trump has proven that he can't change and will always be what he is. In the last month or two, he has become even more of a loose cannon.
