I think the author has it all wrong. By taking this action right after the 2014 elections, Obama pretty much guaranteed that this whole issue will be completely off the table by 2016 and won’t even be discussed in the 2016 campaign.
I disagree. Barring a collpse of the economy or some real foreign policy problem (both of which are quite possible under Barry I), this issue will be the most important one of the campaign. Remember, after the '86 immigration bill, illegal immigration exploded. I believe that the same will happen in the next couple of years, and with increasing speed as Barry I's term comes to a close and fear of the EO being rescinded grows. More immigration = more crime, more disease, more welfare, more state and local problems with school and medical costs, etc.
It isn't going away, its first getting warmed up.
