I see Europe and Canada rallying the rest of the world to intervene to take him out if he manages to "win".
Who? Brazil, China, Russia, India are all too happy to have Trump in the WH.
African dictators won't mind either.
Europe itself is facing more and more extremism ; mostly right wing, some left. The only difference is most of our systems are built to cope with multiple parties. It's the two-party systems where one is successfully hijacked by the extreme that things go wrong - the US and the UK primarily, though Italy and France aren't far behind, each in their own way. Poland, Hungary, Ukrain, Belarus, are all already led by crypto-fascists or despots.
We're currently living the end of a system and a world order. Trump is a symptom, not the disease. The Tea Party, conspiracy theories made mainstream, a public filled with propaganda, a global system built on exploiting the poor, first at home and later abroad.
The middle class of the twentieth century is disappearing again, and we're all feeling it. Either you can keep up, or your fall behind. The well-educated, rich, successful are a small group, the regular blue collar workers are being abused by the rich and, especially in the US, don't manage to work together or don't believe in socialist solutions anymore.
This probably started in the late nineties. These are death throes. It'll get worse - far worse, I think - before it gets better.
When we emerge on the other side, it'll be in a different world. We can hope, pray and work to make it a better world, but I honestly expect a distopia where large parts of the population will suffer, live in nearly uninhabitable areas, under a heavy boot which they be forced to lick for subsistence.
