If the election is close, as it looks like it might be, then there is no controlling authority that the people in the US will trust that could call the election. There is a high likelihood that half of the people will regard the election as illegitimate no matter how it goes for one reason or another such as Russian involvement or the corruption of the DoJ. It's a recipe for civil unrest and disorder.
JustOneMinute: If You Are Not Nervous About The Upcoming Election...
(Yawn)...not for me. I have experienced "raw fear" and this is not it.
Our wonderful American system only allows the winner to be in power for four (4) years before that power is contested again.
Even while in power, there are all kinds of checks and balances to limit that power.
Just ask Obama how powerful his pen and phone were....not much.
I do, however, get the gist of the OP. Massive unrest and possible violence. Maybe among inner city blacks, who have a history of such things, but not anywhere else.
No matter who wins, it will be business as usual for almost all of us.
Even those that swear to run to another country will not do it. That's just bar talk.
The pendulum is swinging to the right and will for the next four to eight years, and the liberals will gnash their teeth, post on Facebook, and pull at their clothes,
... then it will swing back to the left again, and the conservatives will bring up all manner of conspiracy theories and bring up false charges.
Rinse, repeat.
That is how we do it here.
