I mean, it makes sense, even if I'm not happy about it. Most voters have forgotten about COVID, which is just like forgetting about deadly mass shootings, just on a much larger scale. People have forgotten how much of a disaster Trump's first term was, and don't realize that there's every indication his second term will be far worse.
According to 538 Bidens JA has a net negative of -17. If that's the same at the end of June/beginning of July Biden is in serious trouble.

And if you look at Historical Trends here Pres Biden is already headed for Defeat.
Republicans have labelled Biden the 2nd coming of Jimmy Carter and it's hard to argue against that for now given these sort of Numbers.
All the pre-Obama numbers (at a minimum) are garbage when judging the present-day United States. American politics used to take place in a world where supporters of both parties could and did publicly approve of politicians from the other party if they liked them. In the post-Trump era, Republicans would not give favorable approval ratings to Jesus H. Christ himself, unless he had an (R) after his name and licked Trump's feet the way the rest of their "leaders" do.
That said, in 2020, Donald Trump was a not a traitor ineligible for office, and the GOP had not successfully overturned
Roe via the illegitimate Roberts Court.
