A Problem

That's the problem for them. Donald Trump is the President of the United States, subject to the Constitution and the will of the electorate, and not the American manifestation of Big Brother. Socialists are inherently parasitic and thus cannot take "no" for an answer to their demands for obedience and the material goods they need to exist. If they did so they would wither away and die.  A dictator, on the other hand, does not have to take "no" for answer. Thus socialists are by necessity inclined to favor dictatorships over citizen-ruled republics.  When they see a dictator in the dock, they see their own hopes and desires go with him.
