As we've discussed a number of times, even if Trump wanted to make this wall, he legitimately couldn't. The border runs across a lot of private property, the owners of which have said they're not interested in selling or allowing a wall to be built on their property. So you need to have all kinds of imminent domain cases that just never would work out. And that's not even to mention the 118 miles of border that's inside Big Bend National Park, which you can never get approval to build a wall in.
