I am not so skeptical. I suggest that Donald Trump is most likely a "blip" - the most likely scenario is that reason and America's strong institutions will prevail. In 10 years, I would bet we will look back on this time and both shudder and laugh.
The people who I think will not be laughing, however, will be those who had publicly identified as defenders of Mr. Trump's behaviour (here, I am being careful to distinguish between Mr. Trump's inane personal comportment and his policies). These people, I will suggest, will, and rightly so I suggest, be objects of ridicule.
Here's the thing: right now, it is perhaps understandable that some still defend Trump - after all, he is "their guy" and it may well be that these Trump supporters have been treated roughly by others. And we all get our backs up when challenged.
But you (Trump supporters) need to take the long view. In 10 years, when your 8 year old grand-daughter looks you in eye and asks "Grandpa, how could you have supported that awful man?", what are you going to say? At that point, all the squabbles you are engaged in today will be forgotten, and all we will have is the video and twitter record of the utterly abominable behaviour of this President. I would not want to be in the awkward position of being a Trump supporter at that time.
