Loyalty and devotion are among Trump's most persistent fixations...
The cause to which Trump desires such devotion, of course, generally seems to be the success and popularity of Donald Trump. This was clearest during his presidential campaign, when he asked audiences at rallies to raise their right hands and solemnly swear that they would vote for him. At one rally, in Vermont, people were required to profess their support before even being allowed inside.*
But Trump himself prefers to keep his options open, and his allegiances can be quite malleable. His tendency to wash his hands of ties is widely noted, running all the way back to the 1980s, when, according to a secretary employed by Cohn — the mentor whose loyalty Trump so praised — Trump responded to Cohn’s learning of his own H.I.V. infection by severing professional ties. Trump’s ideology is just as famously flexible... There’s no clear pattern to his changing sympathies, which means that when he demands your loyalty, you cannot quite know what it is that you’re signing up for.
