Re: Easily solved
they can save costs by only building one side of the wall. or maybe project the image of a wall, like a hologram. or maybe just say it's being built, mow down a few bushes and drag it out till everyone forgets about it.
the issue is there isn't enough blue-sky, flying-unicorn ideas being presented to appeal to Trumps voter base. this is trump politics. trump is a bullshit artist. so the solution is to sell bullshit. noone (least of all trump) was actually expecting to have to *do stuff*.
