The major problem—one of the major problems, for there are several—one of the many major problems with governing people is that of whom you get to do it; or rather of who manages to get people to let them do it to them. To summarize: it is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it. To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job.
It’s not about saying Biden is to blame. Trump 100% should have blame.
But the fact that someone else STARTED (or in this case re-started) a bad thing doesn’t mean the next person in power gets a free pass for not working to stop it again.
So it’s perfectly fair to call out Biden for not stopping the bad thing that Trump (re)started.
