I'm trying to take the long view. I don't care so much about attacking or defending Biden, since he wasn't my choice for president in the first place. Whatever people want to say about his decisions, and his strengths or weaknesses as a leader, my real concern is who comes after him. If he ends up being perceived, justly or unjustly, as a failure, it could mean a Republican demagogue, perhaps someone even more dangerous than Trump because more committed to an insane, toxic ideology, sweeping into office.
So for the country's sake, not Biden's, I want him to be viewed as an at least reasonably capable president. Even if only to hand over the reigns to another Democrat after a single term.
