It may be obscure, but it cut at the heart of Obama’s MO.
It seems to me that many of Obama’s executive “actions” could be challenged and defeated based on the fact that they’re not executive orders.
Basically, he’s probably going to have to acquire a couple of lawyers now to sit in the midst of the White House and figure new gimmicks to make the EO situation work for the remaining two years. It’s not just immigration that the judge throw the rock at...it could be used as a defense in most other EO actions as well.
