From New York Magazine by Jonathan Chait:
It is widely known that Trump — whose political profile over the decades has vacillated from liberal to conservative to moderate to populist, and supported and opposed abortion rights, higher taxes on the rich, and universal health care — does not care very much about political ideas. This explanation is true, but incomplete. The president also does not know very much about political ideas. And it is not merely the details of policy that he lacks. Trump has no context for processing ideas. He does not understand which kinds of ideas imply support for which kinds of policies, nor why political figures tend to believe what they do, nor why they agree or disagree with one another. He is capable of forming strongly held beliefs about people in politics, but he does so in entirely personal terms. Trump’s flamboyant, weird ignorance reveals a distinct pattern. He is not so much nonideological as sub-ideological.
It is common to attribute Trump’s protean [my emphasis] identity as simple self-interest: He has aligned himself with whichever party seemed to benefit him at any given moment. And surely calculation plays a role. But it cannot explain all his puzzling statements about politics. Sometimes he expresses openness about unpopular policies his administration and party would never go for (like a higher tax on gasoline). Trump constantly relates questions about politics back to himself and his alleged deal-making genius not only because he’s a narcissist, but because the contest of political debate remains largely mysterious to him.
Did You Know?
Proteus was the original master of disguise. According to Greek mythology, the grizzled old shepherd of Poseidon’s sea creatures possessed the gift of prophecy but didn’t like to share his knowledge. Proteus would escape those who wanted to question him by changing his shape. The only way to get a straight answer from him was to sneak up behind him during his midday nap and hold onto him (while he frantically changed from shape to shape) until he eventually revealed what he knew. The adjective “protean” describes anyone or anything that is as mutable and adaptable as the mythological shepherd.
Or, you could just sneak up on Trump while he’s watching Fox News.
