If Trump were merely competent...

... he would be a lot more dangerous. And a bunch of DACA recipients would probably be preparing for deportation today.

SCOTUS today overturned Trump's decision to end DACA because he didn't follow procedures required by the Administrative Procedure Act, which guides executive branch rule-making. If Trump and his lackeys had simply crossed their Ts and dotted their Is, it's a good bet they would've won today.

This is the pattern: 

I'm not sure that it's possible to elected a version of Trump that is more competent and less given to shortcuts -- Trumpism, to a large degree, is a set of impulses more than an ideology -- but just imagine if that actually happened. If somebody with Trump's inclinations and a bit of self-discipline took the White House (say, somebody like Tom Cotton or Tucker Carlson) they would probably be much more successful at turning their inclinations into actual public policy. We're not dodging Trumpian bullets because he's wrong, but because he's so bad at the actual business of governing. That's too close a call.
