Trump’s attack on the integrity of the entire process, which resonates to this day with tens of millions of Americans, is a unique danger to the domestic power of the regime.
It's not the "integrity of the entire process", it's the integrity of the 2020 process. Something that is ignored (at the basis of Trump's election arguments) is the fact that the Governors (using COVID as an excuse) in many of the red states enacted Executive Orders that superseded states election laws and allowing for the mostly unchecked mail-in ballots that (according to his arguments) gave those states the ability to accept more ballots that would have normally been disqualified. That is why since the 2020 election, many states legislatures have bolstered the laws to keep Governors in check when it comes to election laws. Again - SF can't plausibly see how anyone would actually believe that Joe (hidin) Biden could have somehow/someway (legally) garnered more votes than any President in history.
