His point is about the legitimate powers of the executive. The very reason for the separation of powers.
You can't be accepting of what President-Elect Trump has done without being accepting of what President Obama has done, as each had the same mandates given their elections. The same goes for all future presidents, and their eventual actions.
The Executive branch is the most dangerous branch to vest with unilateral powers, as it is the most consolidated; and whatever powers you vest your guy with will eventually be vested with a guy who is decidedly not yours, which is what Democrats are dealing with today.
But my all means, double down.
EDIT: Perhaps I shouldn't put words into LA's mouth, but that was what I inferred his point to be, and it's certainly my point.
