How so? What's the worst that would happen to America if Trump is president four more years?
Be honest.
The destruction of a functioning government will be complete as he bends it to his personal whims (such as using the Post Office to go after Amazon). Its inability, such as dealing with a threatening pandemic will extend, as it is extending now, through all reaches of government as cabinet officers increasingly become his personal servant, as Barr is now.
Millions will lose healthcare.
Attacks on Social Security will continue.
Pollution will continue to increase. Opportunities for entrepreneurship in healthier energy will continue to be discouraged as he focuses on propping up big oil, giving other countries an immense economic advantage over us.
Policies that enable the rich to get richer and everyone else stagnating will continue.
College will remain out of reach for many Americans.
Attacks on the first amendment will grow through more threats and lawsuits.
Our standing in the world will continue to decline through his withdrawing us from it.
The feeling of empowerment will continue to grow for Neo-Nazis and white supremacists, increasing racial violence.
Women will lose control over their bodies.
Our population will stagnant due to his immigration policies, which has a deleterious effect on the economy.
The pandemic serves as a fair warning, as Trump is showing he would take the whole country down in an effort to not lose this Fall. His nihilism will not go away.
