Is the Trump we've seen the tip of the iceberg or is what you see what you get? What about Gary Johnson? Is there more there there out of sight or is he all there is? How can you base anything on what you can't see and what you don't know about someone or what may be coming down the pike or chasing someone from long ago? You only know now not before or after and even now could be distorted completely. Couldn't it?
I've just stopped bothering with US politics after Bernie endorsed Hillary. I don't think you'd be comfortable with me telling you my actual political orientation (or is it already obvious), but though I'm still involved with politics, this whole election has become a circus. It's the first time I actually get to vote, and it becomes the looniest election there ever has been with the most despised candidates in election history. Occasionally I'll follow up on the election just to see what's going on, but the closest party to my politics is the Green party, so I'm voting for Jill Stein. Aside from that, I want nothing more to do with American politics. It's become such a sh*tshow that I have no idea what is satire and what is reality anymore.
With metaphors, one can project their own thoughts and beliefs onto the subject at hand. This is especially true of politics. People read and hear what they want to hear, even if it's not what was said at all. People hate their worldview being shattered, so they try their best to ensure that it stays the same.
I don't want to guess how it'll end either. All I can tell you is that it's going to end badly. Both candidates are crappy evil people, but there is one good thing about Trump. He has exposed how many awful, racist, sexist, and all around disgusting people there are in this country. And that, as you said, ain't a bad thing either.
