Trump was unfit because of how his every public utterance was 100% driven by his own self interest. He was unfit due to his nonstop abrasive demonization of our national institutions such as the intelligence community when they opposed him in any way. Because of his generalized and highly unpresidential demonization of a great many of his fellow Americans. For his willingness to leverage the worst human traits in others for his own self interest. And for his unceasing efforts to divide the nation.
Not for his executive orders or his legislative actions. Not because of the pandemic. Not because of any specific policies, regardless of if I agreed with them or not. For example, I disagreed with a lot, but not all, of his foreign policies. But that is NOT part of why I consider him unfit. I disagree with, or am highly skeptical of the value of, lots of policies of all presidents, regardless of party.
Biden appears to be similar to all the other presidents we’ve had, of both parties. He is deeply flawed, highly imperfect, and is surely making tons of mistakes all the time. And, like all those other presidents, of both parties, except Trump, he tries to avoid intentionally generalized demonization of large groups of his fellow Americans, or broad demonization of our intelligence agencies or of other US institutions.
Biden seems about as unfit to be president as almost every other president in modern history, except Trump,which is to say somewhat unfit. Trump was far more unfit than all the rest combined. I was equally fine with pretty much all those other presidents, regardless of party.
I can say this, with Biden, as with all presidents: I am very glad that we have term limits.
