I did my undergraduate thesis on King Edward VI of England, and the coups (attempted and successful) against his two Lords Protector. A Lord Protector watches over a King basically by being acting King until the King reaches majority around age 18. Edward died at 15, so his Lords Protector were really the monarchy for the six years Edward sat on the throne.
Fast forward 450 years, and it looks like we're back to that arrangement:
[President Trump is] still unprincipled, ill-informed, lazy, and mercurial. Trump continues to act like a 13-year-old trapped in the body of a 71-year-old world leader, as if his prefrontal cortex never developed beyond adolescence. Trump is all libido, lacks impulse control, and is prone to poor decision-making.
By this account, Trump is so immature that he needs his media diet and social life heavily controlled; he can’t be trusted not to make a rash decision based on the incomplete or conflicting information he’s given. In other words, he’s a man-child more than a world leader.
Giving this much power to Kelly is disturbing for a number of reasons. If [Chief of Staff John] Kelly did control Trump, that would make the presidency closer to a monarchy with a child ruler, with the real power residing in close advisers. Moreover, despite claims that Kelly is a non-ideological pragmatist who runs a tight ship, there’s little reason to trust him; he can be as extreme as Trump’s other advisers. According to The New York Times, in a discussion about the fate of the Dreamers, Kelly “likened Mexico, one of the United States’ most important trading and law enforcement partners, to Venezuela under the regime of Hugo Chávez, the former leader, suggesting it was on the verge of a collapse that would have repercussions in the United States.” This is a false and hysterical view of Mexico, one of the most stable democracies in Latin America.
In short, Kelly is trying to exert a level of power no White House official should have, and he’s not even succeeding.
Woe to thee, O Land, when thy King is a child, and thy princes eat in the morning.
