"Biden’s presidency was an informal and unacknowledged regency. Biden himself did not have the mental capacity to rule on his own, and so a confined circle of close advisers and family effectively directed the actions of the presidential office on his behalf.

"Importantly, this regency was not “the White House” or “Biden’s staff” or “the Democratic Party” in general. It was much smaller than all of those things. The regents worked hard to obscure Biden’s dementia from Congress, from large parts of Biden’s own campaign, from the Democratic Party and from many others within Biden’s White House. They ensured that even internal meetings unfolded in highly scripted and predetermined ways, so that cabinet and other officials could not gain a clear idea of Biden’s mental state. They berated and intimidated anyone voicing concern about the president’s health behind the scenes. And they had very simple reasons for doing all of this: If Biden’s dementia were to become common knowledge and not merely an object of private suspicion (however widespread), the regency would be shown up as illegitimate and potentially broken.

"Regents exercise power by restricting access to their charge and restricting their charge’s access to information and the outside world. It is thus unsurprising to find that Biden’s regents subjected him to strict social isolation, particularly towards the end of his term."
