The same story. Well he doesn't mean a wall. He means an idea. Well he means policing. Well he means a wall in some places but not others. Well he means a wall the entire way. How can we negotiate when the goal post is constantly moving and one side has no idea what it wants?
Also just think about it. People travel hundreds of miles and you think a wall will stop them. Is an ocean stopping migrants from Africa entering Europe? Like I said people smuggle in, cross on boats, tunnel under, climb over, or simply fly over in a plane to visit and simply decide to stay. I would say almost no wall regardless of how strategically placed is a good investment. If you want to talk border security or immigration most people on the Democratic side are very reasonable to these issues but the discussion has to start rooted in reality and facts, not in campaign slogans from a guy they didn't even want in the first place.
