We've been an embarrassment for a long time.  And you can look forward to many more Trumps in the future because this is the shit you get after decades of politicians promising shit they could never hope to deliver, and engaging in wars they couldn't hope to win.  It's a rich tapestry of shit to which we've all contributed through apathy, greed, and stupidity.  I can't think of a better gold plated figurehead to run this garbage scow of a country into the iceberg it deserves that a king clown like Trump. | 
	
 There's a lot of stuff in your post I find interesting, ranging from things I agree with to those I think are just plain wrong (but in an always-endearing Sebby-like way).  But I'll focus just on the last paragraph.
I agree that Trump's positions now have little bearing on his positions later.  He's a personality candidate -- more like Putin than anyone I can think of.  But that doesn't mean he'll be a moderate.  Moderates have to build consensus and work across party lines.  And moderation is boring.  
My suspicion is that he'll do things that appeal to the largest group of the loudest people.  Not good.
And I don't think this is a legacy of promises that can't be kept (for that, see Sanders).  Rather it's a legacy of politicians -- primarily Republicans -- behaving as if standing on hard ideological principle and winning elections was the only thing that mattered, and governing was not.  
Immigration reform is the great example.  Many Rs knew it was needed, many supported it.  But above all, they feared that actually enacting immigration reform would give Obama a "win", and that was unacceptable.
