My view is that Obama will do whatever the f*** he likes, and neither the courts nor congress will step up to stop him.
It’ll be for the next president (hopefully Cruz) do undo the damage - which will, in any case, be a long and tedious process.
F.D.R. was a far more popular president than Obama ever was and thought he could do whatever he wanted too, but the courts put the brakes on him. I think that history lesson is instructive.
Obama has overplayed his hand IMO and is about to get slapped down on this issue which is very important to him. But despite this loss, he’ll keep pushing the envelope of course. He’s power mad and obsessed with “transforming” the country into one of his own making.
This issue will likely wind up in the Supreme Court but it should be resolved by early summer.
