. . . against the insurrectionist Donald Trump and all of his idiot minions in his mob as well as in the House and Senate (to the extent that they supported his insurrection if they did) etc.: had Garland done his job, Trump would have been in prison for the insurrection and not in the White House now.
That person ( "emptywheel" ) can have her opinion, but the political aspect of everything ended when Biden defeated Trump in 2020. Staging an insurrection merits prison. Garland failed to seek justice and was not the AG that the US needed. None of the pursuit of Trump for his insurrection would have been anything but support for the continued existence of democracy in the US. ( Note where we are now. )
Beyond the insurrection, Trump purloined classified documents. Anyone else would have been arrested for that and likely nearly immediately. That is a separate situation for which Trump deserves jail time.
It should be expected of the next AG to pursue justice to the point of seeking an indictment of Trump for his insurrection, etc. and should also seek to re-imprison his minions for their 1/6 Insurrection under new and separate indictments, if needs be.
P.S.: Your "reminder" has no basis in actual reality--it is just your best guess or estimation of how things would have gone. You have no special knowledge to present, just your opinion. Furthermore, if the Democrats want to win elections, more is needed than a "the other side is bad" or a "the macroeconomic stats are great" or a "you know, I just cannot talk to Palestinian-Americans, so I'll just avoid them" approach: candidates who lose have campaigned poorly by definition, and GOTV cannot help that, IMO.
