It is only a problem because Trump is trying to get a wall built. Surely you have see the videos from the past showing the dim leaders talking about how bad illegals are for the U.S. So no, it has not become a major problem now, but that is what you are led to believe. The dims are strictly looking at the votes, plain and simple.
The great Ronald Reagan said that a nation without borders is not a nation at all. Kind of what we are, wouldn't you agree. Stop being led to believe that this has just now become an issue. You're just following the lead that the dims want you to follow.
