He can only hold off on enforcement. The law goes into effect on the date stated in the statute. Period
Can Obama really prevent enforcement in 2014? I think not. Again, what is a Judge going to say when presented a case by a prosecutor? "We'll go with what Obama says rather than the Text of the Law"?
We forget that there are tens of thousands of hungry lawyers all ready with their sharpened knives out for business red meat. "Deep Pockets" you know are lucrative they say.
And "Overly" zealous prosecutors looking to make their marks.
And don't forget the Press. They're hungry too and want their red meat also. They'll ignore the Emperor's new clothes for now. But wait for the cry "But he has no clothes on!".
Just wait.
