If it doesn't blow before the 2020 election, I can guaranty that it will blow during Trump's second term. This is it. Like you said - within 5 years. Trump's job, being the everything-in-chief, will be not only to transition out of it but to do that while explaining to the American people that it was not his fault. He will have to explain it over the calls for his head by the partisan media. WE HERE know it's not his fault, but for every one of US, there are ten heads in the sand. I don't know how this will play out. Hell, I don't even know how to keep the attention of my friends and family when trying to explain this.
