As Q has stated many times directly and indirectly, the border wall is absolutely CRUCIAL for the following reasons:
Cuts off Democrat votes through illegal aliens
Cuts off drug money from drug mules smuggling drugs.
Cuts off hit squads via MS13 and terrorists
Eliminates the siphoning off of American wealth through illegal aliens taking jobs, not paying fair share of taxes, abusing welfare programs and sending billions back to South American countries.
A full border wall would be a huge win for the prosperity and security of USA.
