Be careful, aliens, you might get what you asked for. If they get legal status, they will probable lose their jobs because they will compete with Americans. Wages will go up. The number of jobs offered will be less and businesses will hire Americans before immigrants. This has always been the norm.
But of course, there is no chance in hell that they will be made instant legal citizens. They will have to wait their turn. A long wait.
The only reason aliens are in demand is they will work for low wages and therefore can be hired in larger numbers. If made legal the wages will rise and demand will drop many will be out of jobs. Any job in Mexico will look better than no job in America.
They are threatening with votes, but they normally vote democrat anyway, so it will not matter. What votes will matter is democrats who normally vote democrat will vote republican. Like me. Democrats will lose votes.
