So, Trump is having trouble with
1. White House staff
2. Federal bureaucracy
3. Congress
4. Courts
5. Media
6. Protests / Public Opinion
7. Other Countries, including Allies
8. Some businesses in the US bailing on him
9. The intelligence community
So, what's supposed to be his strength again? What else is there to the job of President?
Maybe one good thing to come out of this disaster of a Presidency will be to kill this "run government like a business" nonsense once and for all.
We can only hope.
A few points there
2 Some of the federal bureaucracy doesn't like him and is resisting him because his agenda is opposed to their ideological and class interests as the bureaucratic class. (The same is true of 9 and some of the issues with CIA leadership) Once measures are brought in to reestablish his executive authority and expand the proportion of Federal bureaucrats employed at will by the President from 2% to 100% that problem should then become largely soluble
3 The Democrats in Congress are largely opposing him. He's getting on just fine in getting his way with the Republicans who hold majorities in both houses.
4 Liberal activist judges are trying to gum up his actions. That's been covered above
5 Liberal and left wing media oppose him, conservative and right wing media support him
6 You are conflating two things there. His approval rating polling isn't great at the moment but then it wasn't great during the election. Public opinion is strongly divided on the President.
Protests on the other hand are not a reflection of public opinion. Of course you've had the very large 'women's march'. The attendees there are the kind of leftists who would enjoy a big jolly day out virtue signaling that had been organised for them by Democratic supporting organisations. Such people are not at typical of the public at large and given the infrequency of these kinds of protests not a major problem.
Then you have all the smaller protests using more aggressive tactics like the airport protests. Unlike protests on the right (like anti-abortion activist protests or the Tea party protests) these left wing protests are rarely genuine grassroots efforts and are instead well funded astroturf efforts run by professional establishment funded organisers.
It comes down to style. Americans are not accustomed to a President acting like a dictator. They do not like it. Typically the President tries to reach out to the other side of the partisan divide, but this time he tells people to get in line or get lost because he has all the power.
Because he has nothing in common with the Democrats in office, it is hardly surprising that he gets opposition at every turn. Why shouldn't an opposition party act in accordance with conscience and respect for precedent?
The President cannot order federal judges around. We have an independent judiciary, one shielded from partisan bickering and not amenable to changes in the way that the wind blows. Just because the President urges the courts to hang offender high is no reason for the courts to decide that such is not cruel and unusual punishment.
Against President Obama, Republicans made an early decision to not cooperate. With President Trump Republicans tell Democrats that unless they sell out their principles and their constituencies to the Trump Administration they have no relevance to the political process. It is hardly surprising that liberals resist. This is an Administration with its own Party in nearly-complete lockstep, one that believes in all power to the economic elites at the expense of all else.
