It could get very ugly. You would think that blacks would be begging the Democrat part to put up a wall and crack down on illegal immigration from latin countries.
The prisons are often segregated; while individual blacks will complain about the open borders, their kings have decided to take their thirty pieces of silver and leave them hanging.

Bush knew it, and won twice because of that fact.
