A 2nd century wall in the middle of the southwestern desert in the age of cheap easy to fly drones??? Anyone wanting to spend my TAXPAYER dollars on such a concept is a YUGE idiot!! They have also never been to the desert along the border anywhere (nearly) west of Nogales. Or most places east of Nogales for a good long stretch (100's of miles). That idea (a wall stopping anything in that unpopulated terrain) is completely useless. A waste of taxpayer dollars. How can so-called Conservatives be so stupid with MY tax dollars??
