It’s just in his nature.
Because those of us opposed to Il Trumpe need to focus on what will sway voters, there is the concern that we are being intentionally distracted by Trump’s constant barrage of scandals, great and small. I think, however, Paul Waldman gets it right (boldface mine):
In any case, something tells me there is more to learn about this, and that perhaps it will shed some light on why a well-known adulterer such as Trump was so eager to keep women like McDougal and adult-film actress Stormy Daniels quiet. And who knows what other tapes Cohen has. But I’m sure some people will react to this news by saying something we’ve heard before — that we shouldn’t pay attention to this kind of trivial stuff because there are far more important things going on, and we don’t want to get distracted.
It’s an understandable argument. None of us has an infinite attention span, and it’s often only when a story comes to absolutely dominate the news that people in power feel enough pressure to alter their behavior, as we saw with the Trump administration’s abhorrent family-separation policy (an issue that, by the way, is not yet resolved; there are still hundreds of children who haven’t been reunited with their parents).
But even as we try to make the most reasonable decisions about what’s worth focusing on and what isn’t, we need to make peace with the fact that every serious Trump scandal will be preceded, followed and occasionally upstaged by a trivial Trump scandal. That’s the world we live in, and there’s not much we can do about it. It is not because Trump is such a clever media manipulator that he is able to continually distract us from what’s important. It’s because he is quite simply one of the most comprehensively corrupt individuals now living in the United States — and he happens to be the president.
The parade of scandals and controversies has been unceasing since Trump declared his candidacy in 2015, and it will never stop. If you’re waiting for the moment when things will calm down enough for us to focus on one thing at a time, you’ll be waiting until he leaves office.
As some asshole with a blog noted, narcissism–Trump’s illness–can be advantageous at times (boldface added):
To be clear, being a narcissist can be advantageous: there are times when self-delusional confidence is incredibly useful (if for no one other than the narcissist). Needless to say, the narcissist doesn’t suffer from imposter syndrome (most of the time anyway, when the imaginary show in his head is uninterrupted). And they often have, at the very least, a superficial ability to play to an audience. Erratic behavior, at times, can be advantageous. But the narcissist has an additional advantage–most people don’t know how to deal with someone like this, especially in someone in a position of authority. Most people simply aren’t wired like this (certainly not to this extreme). You are working for and dependent on someone who is mentally ill–and, by and large, is unwilling to seek help (or who even realizes there is a problem).
This really doesn’t get better–or calmer–until he is put in check.
