The worst thing about your statement is that it has to be taken in a literal sense. In past elections, “our country is doomed” if someone won election was just hyperbole. Except for the last one. A lot of us said we were doomed if Trump won. The body count is 218,000 and still rising. The delta point of presidential success or failure is typically an unexpected event, for which he has failed. We are lucky there have been no serious geopolitical or military challenges for him.
If he wins, each of us will have to learn how to manage catastrophe. It will be awful.
