Jonathan Chait puts it well:
It would be tempting, but unfair, to draw a simple equation between Joe Biden’s situational ethics and that of his successor. A willingness to evade the rule of law is the foundation of Donald Trump’s entire career in business and politics, not a nepotistic exception. Still, principles become much harder to defend when their most famous defenders have compromised them flagrantly. With the pardon decision, like his stubborn insistence on running for a second term he couldn’t win, Biden chose to prioritize his own feelings over the defense of his country.
He who is without sin, cast the first stone.
