Meh. I'm #NeverTrump and this video is crap.
He's right about one thing: a "wall" is a stupid idea. One of the worst aspects of a wall, is that it is actually hard to see what is going on on the other side.
Now, a nice Israeli style border fence...
...Oh, yeah. Try to hide a ladder propped up against that.
Cheaper, more effective, and all around better than any dumb wall suggested by dumb candidates.
