It is not the least bit surprising that all
nine justices, including the two dissenters,
agree that the president of the United States
is not above the law
and must comply with lawful subpoenas.
What’s troubling about the decision is that
the court didn’t say,
“And the subpoena may be enforced forthwith.”
Instead, they sent it back to the U.S. District
Court in Manhattan,
where there will be further wrangling over this.
Now, Donald Trump chose to take his complaints
about the Manhattan grand jury subpoena to
federal court, removed it from the state court
in so doing.
The Supreme Court, therefore, could have said, 
“You chose your forum to seek your remedies.
You’ve lost.
And the subpoena is proper.”
By taking this back to a lower court, it has
encouraged further litigation,
which may be very brief or may go on for months.
And that benefits Trump politically.
So, legally, Trump had a big loss — I’m
sorry, legally, he had a big loss.
Politically, he got a win out of this court.
And this decision, I think, also reinforces
a very disturbing trend in the Roberts court,
which seems to be that if you’re wealthy
and can afford more due process, the court
will encourage you to get 
all the due process you want.
That sends a signal to prosecutors and regulators
not to mess with people who are going to fight back
because they will tie up 
your limited resources,
so just look the other way or 
don’t pick up cases like this.
