...and that this suggestion that Biden step down is about realpolitik, about accounting for (not the NYT's words) the stupid way the American public makes voting decisions.

They clearly state that they consider a Trump win a huge threat to the country.

Not calling on Trump to resign is simply knowing Trump, nor the Republican party, have a good side to appeal to for dropping out for the good of the country.

It would of course be better if they skipped over the expectations game and flat out called on Trump to resign too, just to make things more clear and definitive, but I think we all know that would be a futile gesture. Republicans would glory in being told Trump should withdraw by the NYT, so saying Trump should quit the race would be nothing more than preaching to the choir.
