In recent weeks, I have been binge--watching the Netflix show House of Cards (an update of the classic BBC adaptation of Michael Dobbs’ novel). It is addictive and compelling, largely because of the clever dialogue and plot — but also because it sheds light on the presidency of Donald Trump.

This is not just because the show, which follows the rise of an unscrupulous politician called Frank Underwood (played by Kevin Spacey), illustrates the grubby back-room deals often involved in pushing legislation through Congress, nor because its themes are familiar — from infighting among (largely) unprincipled politicians, to battles with terrorism, job-creation schemes, Chinese trade wars and so on.

What I found most thought-provoking was that the drama’s portrayal of Washington DC is exactly what President Donald Trump loves to define himself against. If you want to understand why Trump can’t stop tweeting — and why his no-holds-barred statements are so popular among his base — watching House of Cards is a good start. It throws light on the “oppositional symbolism” that he has used so well; the way he has exploited his outsider status to appear as the opposite of all that is wrong with politics.
