In all honesty, I just don't see any Republicans actually attempting to overturn Barry's ruling by executive fiat, regardless what happens in November.
I think this is one of those things that will remain long after Barry does the duffle bag drag out of the WH.
In fact, I can see Congress actually using portions of this executive plan and legitimizing it by enacting parts of it into law.
On illegal immigration, I have absolutely no faith in Congress whatsoever, irrespective of party. The sheer numbers of illegals have made it a moot point. They'll get their amnesty and their free ticket.
This, despite reports that claim that the flood of illegals has subsided to a trickle.

That may speak to those who aren't yet here, but what about the 11.1 million that ARE here?
