Unfortunately handicapped people have a hard time immigrating to other countries, but I'd consider trying. Not so much for Trump himself but for what it means to the country that it's citizens would willingly re-elect him. For the precedent it would set in the election of future leaders.
I'm generally willing to stay and advocate for the betterment of the home that I love. But when it becomes obvious that your home does not love you, then it gets hard to justify the battle.
9/11 really began the decline of our nation as we broke ourselves upon foreign war and battling a puffed up enemy called terrorism. But it was a slow one. Trump did not start the decline, but he certainly accelerated it by a shocking degree over the past few years. I hate to imagine what another few years would bring.
