The bishop has firmly asserted that God is on the side of the migrants and not those who would terrorize and deport them and he is right.  He went beyond arguing the point, although he did that well, and claimed eventual victory.  The immigration debate has always been a fight within the GOP between the xenophobic racists, those who want to bring workers in under law and those who use the law to bring in workers and use their illegality to treat them like slaves.  As long as the first exists, the third will thrive.  The bishop has made it clear that the first is not a moral stance in the Catholic Church.  

Of course, there will be those who say, but abortion!  Legal abortion does not justify this because those who oppose legal abortion have no plan except to keep those voters in the GOP camp on immigration, taxes and accepting the plutocracy.  To use a phrase from my home state of Texas, they are all hat, no cattle.
