It’s so amusing: the GOP threatens impeachment for the President’s “lawlessness.” However, executive orders and unilateral decision making is a privilege and power of the executive branch. All Presidents have used it, some very extensively.
Ironically, Bush/Cheney argued not only for this right, but demanded far more frequency, scope, and authority for the President: a model of an “Imperial Presidency.” The GOP loved it then – even demanded it then! Now… it’s all distortion and false outrage with them when Obama does it.
Obama is far more conservative about executive power than many other Presidents, certainly more conservative than Bush was. They hobble him every chance they get, then get extra snarky when he works around them.
