If someone like, say, Noam Chomsky was president, the media would be completely ignoring him. Per the Herman-Chomsky propaganda model, if a public figure or nascent public idea really does present a threat to the capitalist system, he, she of it will be treated with dead-silence by the capitalist media - or as Orwell called it "memory holed". This is much more effective than mockery, which as Shakespeare observed (in Hamlet), only draws attention to the possible validity of the object of mocking. This is why one never hears about, even negatively, Chomsky(1), or single-payer, or global warming, among many other things, in the corporate media.
So, the media's over the top jocular coverage of Trump (especially during his campaign) while Bernie Sanders was totally ignored is really an indication that the corporate capitalist media does not consider Trump to be a threat at all to their agenda - probably quite the opposite.(2)
(1)At a local Noam Chomsky award dinner and talk I once attended, the ballroom was packed with reporters - yet the next day - absolutely nothing could be found in the newspapers, TV channels, even the free-weekly tabloid. His previous evening's visit to Pittsburgh and speech never happened - in stark to the attention given to a visit and talk by Henry Kissinger a couple years earlier. It was obvious that the reporters were there just on the outside chance that Chomsky committed some kind of faux pas or remark that would establish him as the "self-hating, terrorist-loving Jew" that they desperately want to stick on him.
(2) This kind of refutes the popular conspiracy theory among the US left of this "deep state of economic elites" who oppose Trump and are scheming to get rid of him, doesn't it?
