A wall is fine where it will work (there are hundreds of miles of wall already, between 607 and 1000), but without enforcement of laws, magnet removal and true policing of the border, they tunnel under, climb over and fly over, and they're waved by at official crossings where there is a wall, or not be sent back when they've made it in illegally (even after committing crimes).
And it's important to acknowledge the VAST numbers who "overstay" their travel and student visa and just stay.
I don’t think that you and I have the same type of wall in mind.
The pitiful sections of wall that currently exist need to come down and be replaced with an actual wall.
I really don’t see any point in discussing this with you, you come across as a complete GOPE drone.
I’m sorry that you believe their lies. What a pity.
All I can tell you is that your candidate and your party aren’t selling anything that I’m interested in buying.
