You abandon the land of your birth only if you are persecuted. (Moving because you took a job in another land is different.) Neither Donald Trump nor Hillary Clinton is going to persecute you.
In fact, if you value your citizenship, you stay and you hold the president accountable for his or actions. You ensure that the foundations of our democracy are not ruined. You ensure that any attempt to grab powers beyond a level of what’s acceptable is prevented. You ensure that your voice and your efforts resonate.
That is, unless you are a weak-kneed wimp.
If you are, you abandon the country.
