All but maybe #5 and #8 require legislation and thus the cooperation of congress (including 60 votes in the Senate to defeat a potential Democrat filibuster). My view is that the most important job of the President is to ensure the effective functioning of the executive branch agencies. This involves selecting good department heads and pursuing effective policies through the exercise of discretion in rule-making and executive orders. This is vital, but largely esoteric and technical stuff. It's also an embodiment of the "system" and the "elites" that Trump campaigned against. I see three possibilities as to how he handles this part of his job: 1. He doesn't actually care and entirely delegates it to people that do, likely the existing right-wing policy apparatus of pro-business, anti-regulation ideologues. The tenor of the agencies changes much as it did under George W. Bush and Dick Cheney, some qualified people leave, but the essential machinery of government continues operating. 2. He delegates the "boring stuff" (SEC, FAA, FDA, IRS, DOE, etc.) per 1 but uses the executive branch machinery to pursue projects that are personally and politically important to him, e.g. leaning on the DoJ to "lock her up" or destroying the EPA. The boring agencies continue to function, but others become plagued by strife and a loss of morale. 3. He blunders, has a health issue, or a serious scandal emerges that politically paralyzes him and nothing happens till he is replaced. Remember, while he's spent a long time in the public eye, he's escaped the usual scrutiny that has been given to the health and financial affairs of post-Nixon candidates.
