Similarly with Trump we have no idea what might happen if he does win. He could end up starting WW3, or call for the end of US Democracy and install himself as dictator (and now we know 50% of the country is stupid enough to go along with that).... or he might just end up a do-nothing president bounced out after 4 years. For that matter maybe he's crazy like a fox and fed the Rs bullshit so they'd get behind him, then turn around and push for a hugely progressive agenda. You never know what Trump might do.
So yes, I predict a short-term crash, a recovery, but after that all bets are off. We're also due for a recession at some point. In fact Trump could be a blessing in disguise as he presides over a recession, bungles the response, and gets him and the rest of the Rs tossed out in 2018 or 2020.
I'm torn about the whole thing because I will personally benefit from Republican control. I've finally made it into the tax bracket where their constant tax breaks for the rich personally benefit me. Long-term their rich-get-richer strategy will lead to anemic growth.
Whoever said "may you live in interesting times" as a curse was right.
