Is the age of rhetorical language long gone?

In listening to the presidential candidates, I am struck by the plainness of the language. Trump, with his frequent use of “huge” and “loser”, is a bit more apparent in this, but the others are not much better. There is not even an attempt to say anything in artful or inspiring way, nothing remotely like the language of the Gettysburg Address or Martin Luther King’s “I had a dream” speech. Bernie Sanders talks of revolution, but the language he uses is rather mundane.

Are we past the use of rhetorical language? Do we expect to hear the common and familiar talk of the man in the street? Would we be put off by anything else? Maybe, but it saddens me a little that there is no attempt to lift us up through more poetic language.
