The way I see it we have one major problem: Trump and his minions are bent on a dictatorship with the erosion of the Constitution. While it is evident in Trump's speeches that he babbles incoherent sentences, like Biden he is showing signs of mental decline. HOWEVER, if Democrats want to win the election and stop shooting themselves in the foot, thwarting their own effort to win the presidency and preserve the democracy, they need to stop picking on Biden, supporting Palestinian- and Iranian-backed propaganda, and so on. You cannot win when you are dividing your own effort.
After the election is the time to face these issues, not when you are trying to prevent a fascists takeover.
