If there is one thing the Trump administration has displayed during the last three years, it is incompetence. That incompetence is fueled by Trump's own narcissism. He sees everything in terms of how it makes him look, rather than what is good for the country.
So far, Trump has been lucky. He has utterly failed on foreign policy and climate change, but those have not yet significantly affected the daily lives of most Americans. And although the economy is not as great as he claims, he inherited an economy strong enough to withstand his incompetence (so far).
But now we face an issue that could easily become a crisis, and we cannot afford incompetence in dealing with it. It is the Coronavirus. If that virus spreads to the United States (and reaches epidemic status), it will affect the lives and well-being of many Americans -- and it could easily trigger a recession in our fragile economy. That would be disastrous for Trump -- and would end his hopes of a second term.
So far, Trump has survived his own incompetence -- but dealing with the Coronavirus demands competence. Trump has demonstrated that is something he doesn't have.
